Abstract
An adhesive film including a first adhesive layer containing a first main resin component and dispersed conductive particles, and a second adhesive layer containing a second main resin component and adhering to the first adhesive layer, each of the adhesive layers containing a secondary resin component, wherein the first main resin component has a glass transition temperature higher than that of the secondary resin component, and the second main resin component has a glass transition temperature higher than that of the secondary resin component and lower than that of the first main resin component, and a reaction peak temperature of each of the adhesive layers is lower than the glass transition temperature of the first main resin component and higher than the glass transition temperature of the second main resin component, and is a temperature at which a calorific value of the adhesive layer is maximum during temperature rise.
