CIRCUIT CONNECTING MATERIAL AND STRUCTURE FOR CONNECTING CIRCUIT MEMBER

摘要

A circuit connecting material is arranged between a first circuit member (30) having a first circuit electrode (32), and a second circuit member (40), which faces the first circuit member (30) and has a second circuit electrode (42), and the circuit connecting material electrically connects the first circuit electrode (32) and the second circuit electrode (42) with each other. The circuit connecting material contains an adhesive composition and conductive particles (12) having a diameter of 0.5-7μm. An outermost layer (22) of the conductive particle (12) is composed of a metal having a Vickers hardness of 300Hv or more, a part of the outermost layer (22) protrudes outward to form a protruding section (14), and the diameter and the hardness of the conductive particle (12) are in a specific relation.
