THERMOSETTING ELECTROCONDUCTIVE ADHESIVE

In the past, it was necessary to add many electroconductive particles in order to improve electroconductivity, and adding many particles caused the initial viscosity to rise and made it difficult to stabilize storage stability. In the present invention, however, selecting monomers makes it possible to improve the electroconductivity even if many electroconductive particles are not added, and usingspecific electroconductive particles makes it possible to stabilize the storage stability. A thermosetting electroconductive adhesive including components (A)-(D), wherein the component (A) is an oligomer having (meth)acryl groups, the component (B) is monomers having one methacryl group in the molecule, the component (C) is an organic peroxide having a specific structure, and the component (D) is electroconductive particles surface-treated by stearic acid. 以往，为了使导电性提高，需要大量添加导电性粒子，大量添加时，在初始粘度增高的同时，难以使保存稳定性稳定化。但是，本发明中通过选定单体，即使没有大量添加导电性粒子，也使导电性提高，并且通过使用特定的导电性粒子，能够使保存稳定性稳定化。一种热固化型导电性胶粘剂，其包含(A)～(D)成分：(A)成分：具有(甲基)丙烯酰基的低聚物
