ABSTRACT:
The present invention is to provide an electrical connection material through which an electrical connection via conductive particles can be performed reliably regardless of a little unevenness of an object. The electrical connection material is an electrical connection material100for electrically connecting an electrical connection portion of a first object4and an electrical connection portion of a second object2. The electrical connection material100comprises a first film-like adhesive layer6which is a film-like adhesive layer arranged on the first object4and is composed of a plurality of conductive particles7, a first binder8containing the conductive particles7, and a first filler F1and a second film-like adhesive layer9which is arranged on the first film-like adhesive layer6and is composed of a second binder9A whose viscosity is lower than that of the first binder8and a second filler F2.
