  • Patent number: 11359116
    Abstract: Conventionally, there was a need to add a large amount of electroconductive particles for improving conductivity, but when the electroconductive particles were added too much, initial viscosity was increased, and at the same time, it was difficult to stabilize preservation stability. However, conductivity can be improved without adding a large amount of the electroconductive particles by selecting a monomer, and at the same time, preservation stability can be stabilized by using certain electroconductive particles. A thermocurable electroconductive adhesive including components (A) to (D): component (A): an oligomer having a (meth)acryl group; component (B): a monomer having one methacryl group in a molecule; component (C): an organic peroxide having a specific structure; and component (D): electroconductive particles which are surface-treated with a stearic acid.
