A battery pack containing a plurality of plate-shaped laminate batteries arranged in a direction vertical to a plate-shaped surface of one of the laminate batteries. The laminate battery contains: a layered body which includes a negative electrode, a separator, and a positive electrode, and is disposed parallel to the plate-shaped surface of the laminate battery; an outer packaging including a laminate film enclosing the layered body; and an electrode terminal which is electrically connected to the layered body and extends from a one side part of the outer packaging. The outer packaging has, in an inside thereof, a battery part having a space in which the layered body exists and a bag part which has a space a volume of which is changeable, communicates to the battery part through a communication part, and is disposed on an other side part opposite to the one side part. The battery pack includes: the laminate batteries arranged in a manner to have the other side part on an upper side of the battery pack in the vertical direction, and to have the one side part on a lower side of the battery pack in the vertical direction; and a power cable for charging and discharging on the battery pack is disposed in the lower side of the battery pack in the vertical direction. The battery pack is a highly reliable battery pack which exhibits the excellent operational stability, i.e., can maintain the high efficiency.


As a divided mold also serving as holding means 40A for both mold parts 11 and 21 in correspondence with a protrusion part of a molded article fastening member 4, a concave mold part 11 has a first holding surface 43 opposed to a base portion of the protrusion part, and a convex mold part 21 has a divided mold also serving as holding member 46 having a second holding surface 45 opposed to the first holding surface 43 and a divided mold biasing means 47 that guides the divided mold also serving as holding member 46 movably in a mold opening/closing direction and constantly biases the divided mold also serving as holding member 46 toward the first holding surface 43, and the base portion of the protrusion part of the molded article fastening member 4 can be held between the both holding surfaces 43 and 43 by the divided mold also serving as holding means 40A in the state in which the both mold parts 11 and 21 are completely closed and the state in which a cracking clearance CL is left between the both mold parts 11 and 21. This makes it possible to prevent the occurrence of burrs in the base portion of the protrusion part protruding laterally from the foam-molded body.

The present invention has an object to provide a planar light-emitting panel attached with a jacket to protect edges of a light-emitting tile, while the jacket is prevented from being peeled off or removed from the light-emitting tile. The planar light-emitting panel includes the light-emitting using a glass substrate as a base, and an elastic jacket covering end faces of the glass substrate. An emission surface is provided on a front face of the light-emitting tile. The elastic jacket has a rear face side opening, on a rear face side of the light-emitting tile. On opening edges of the rear face side opening, when viewed from rear, a plurality of jacket side protrusions protruding toward a center side of the rear face side opening are formed. The jacket side protrusions are separated at predetermined intervals along the opening edges.
