摘要:
There is provided a conductive paste obtained by kneading conductive particles into an epoxy resin and having good filling ability into a via hole, which can form a connected portion wherein the connection resistance does not change with time even under high temperature and high humidity conditions. Also, there is provided a method for manufacturing a multilayer printed wiring board using the conductive paste.A conductive paste containing conductive particles and a resin mixture wherein the content of the epoxy resin having a molecular weight of 10,000 or more is from 30 to 90% by weight in the total resin component and whose elastic modulus at 85° C. after curing is 2 GPa or less, the content of the conductive particle being from 30 to 75% by volume. Furthermore, a method for manufacturing a multilayer printed wiring board using the conductive paste.
