Patent ID: 8710662

Claim:
A light-reflective anisotropic conductive paste used to connect a light-emitting element to a wiring board by anisotropic conductive connection, the light-reflective anisotropic conductive paste comprising a thermosetting resin composition, conductive particles, and light-reflective insulating particles, the conductive particles and the light-reflective insulating particles being dispersed in the thermosetting resin composition, wherein the thermosetting resin composition contains an epoxy compound and a thermal cationic polymerization catalyst-type curing agent in the form of an aromatic sulfonium compound represented by the formula (1): where in the formula (1), R 1 is an aralkyl group, R 2 is a loweralkyl group, and R 3 is a hydrogen atom or a loweralkoxycarbonyl group, X represents a halogen atom, and n is an integer from 1 to 3.
