Title:
異方性導電フィルム
Document Type and Number:
Japanese Patent JP7039883
Kind Code:
B2
Abstract:
An anisotropic conductive film has a structure in which high hardness conductive particles having a 20% compression elastic modulus of 8000 to 28000 N/mm2 and low hardness conductive particles having a lower 20% compression elastic modulus than that of the high hardness conductive particles are dispersed as conductive particles in an insulating resin layer. The number density of all the conductive particles is 6000 particles/mm2 or more, and the number density of the low hardness conductive particles is 10% or more of that of all the conductive particles.
