[Problem] To provide a glove base and glove which enhance water-absorbing properties for moisture on a surface of a hand and easily release moisture to the outside from the entire glove even if the glove is configured only of a fiber-made base or even if coating is provided to a surface of the glove. [Solution] A glove base of the present invention is a glove base made of fiber and having a hand shape, wherein water-absorbing properties of a first fiber exposed mainly to inside of the glove base are higher than water-absorbing properties of a second fiber exposed mainly to outside of the glove base, the first fiber absorbs and moves moisture on a surface of a hand on the inside to the second fiber, and the second fiber moves the moisture moved from the first fiber mainly in a surface direction.

In a resin molding device (1), a lower mold (4) includes a side surface member (8), and a bottom surface member (9) which can be moved up and down inside the side surface member (8). Substrate pressing pins (17) are provided in the bottom surface member (9). A substrate (6) having a through hole and a connection electrode portion formed therein is fixed to an upper mold (3). The lower mold (4) is moved up to bring tip portions of the substrate pressing pins (17) into close contact with predetermined regions where the through hole and the connection electrode portion are formed, and press the predetermined regions. By moving up the lower mold (4), the substrate (6) is clamped by an upper surface of the side surface member (8), and the predetermined regions are further pressed by the substrate pressing pins (17). Since the substrate pressing pins (17) press the periphery of the through hole and the surface of the connection electrode portion, it is possible to prevent a fluid resin from entering the periphery of the through hole and the surface of the connection electrode portion. Therefore, the surface-exposed state before resin sealing is performed can be maintained, with no sealing resin being formed at the predetermined regions.

Resin sealing apparatus and method of sealing a substrate. A lower mold (18) facing an upper mold (13) has a bottom surface member (22) for a cavity and a side surface member (23) for the cavity. An upper end surface of the bottom surface member (22) forms an inner bottom surface of the cavity (24) and has a planar shape corresponding to an unusual planar shape of a sealing resin (R2). The side surface member (23) and the bottom surface member (22) can slide relatively. A substrate (19) is disposed on a mold surface of the upper mold (13) such that a component (19a) to be sealed attached to the substrate (19) faces downward, and the cavity (24) is filled with a fluid resin (R1). The upper mold (13) and the lower mold (18) are clamped, and the component (19a) to be sealed is immersed in the fluid resin (R1) filled into the cavity (24). Then, the bottom surface member (22) is raised, and the fluid resin (R1) within the cavity (24) is pressed at a prescribed resin pressure and cured to form the sealing resin (R2). The bottom surface member (22) and the side surface member (23) are moved relatively, and thereby, a molded product (M) having the sealing resin (R2) is released from a mold surface of the lower mold (18).


The present invention provides a method for producing an electronic component, capable of simply and efficiently producing an electronic component having both of a via electrode(s) (bump(s)) and a plate-like member. The method is a method for producing an electronic component. The electronic component includes: a substrate 21, a chip(s) 31, a resin 41, a plate-like member 11 having a surface(s), a bump(s) 12 that includes a deformable portion 12A, and a wiring pattern 22. The method includes: disposing the chip(s) 31 on the surface(s); and encapsulating the bump(s) 31 in the resin 41. The encapsulating includes: encapsulating the chip(s) 31 in the resin 41 between a bump 12-formed surface of the plate-like member 11 on which the bump(s) 12 is formed and a wiring pattern 22-formed surface of the substrate 21 on which the wiring pattern is formed; and causing the bump(s) 12 to be in contact with the wiring pattern 22.


The present invention provides a method for producing a resin-encapsulated electronic component, capable of simply and efficiently producing a resin-encapsulated electronic component having both of a via electrode(s) (bump(s)) and a plate-like member. The method includes a resin-encapsulation step of encapsulating at least one electronic component in a resin. A produced resin-encapsulated electronic component includes: a substrate; the at least one electronic component; the resin; a plate-like member; and at least one bump. A wiring pattern is formed on the substrate. In the resin-encapsulation step, between a bump-formed surface in a bump-formed plate-like member obtained by forming the at least one bump in the plate-like member and a wiring pattern-formed surface in the substrate, the at least one electronic component is encapsulated in the resin, and the at least one bump is caused to be in contact with the wiring pattern.
