Provided are an adhesive agent having excellent bonding properties with oxide films and excellent heat-dissipation properties and a connection structure using the same. The adhesive agent contains an epoxy compound, a cationic catalyst, and an acrylic resin containing acrylic acid and acrylic acid ester having a hydroxyl group. Acrylic acid in the acrylic resin reacts with the epoxy compound to generate connections between an island of acrylic resin (13) and a sea of epoxy compound (12) and roughen the surface of an oxide film (11a) to improve an anchor effect with the sea of epoxy compound (12); solder particles (1) contained in the adhesive agent are melted to form metal bonding with an electrode (10), thereby enabling improvement in adhesive strength between the adhesive agent and the electrode (10) and further improving heat dissipation from a surface of the metal bonding.

Provided is an anisotropic conductive adhesive in which excellent optical characteristics and heat dissipation characteristics are obtainable. The anisotropic conductive adhesive contains conductive particles (31) each comprising a metal layer having Ag as a primary constituent formed on an outermost surface of a resin particle, solder particles (32) having a smaller average particle diameter than the conductive particles, reflective insulating particles having a smaller average particle diameter than the solder particles and a binder into which the conductive particles (31) solder particles (32) and reflective insulating particles are dispersed. The conductive particles and the reflective insulating particles efficiently reflect light, thereby improving light-extraction efficiency of an LED mounting body. Additionally, inter-terminal solder bonding of the solder particles (32) during compression bonding increases contact area between opposing terminals, thereby enabling achievement of high heat dissipation characteristics.
