ABSTRACT:
A connection sheet which firmly bonds electrodes that face each other together by interposing the connection sheet between the electrodes. The connection sheet comprises a first adhesive layer containing a first adhesive having an insulating property and a second adhesive layer placed at least on one side of the first adhesive layer and containing a second adhesive having an insulating property and a conductive material, wherein at the time of electrode connection, the second adhesive molten has a viscosity equal to or lower than that of the first adhesive when molten. When the electrodes are connected with this structure, the conductive material contained in the second adhesive layer is embedded in the first adhesive layer having relatively high melting viscosity, and part of the conductive material is trapped on the electrodes to be connected in contact therewith. Accordingly, the conductive material can be securely held between the electrodes. Further, since the region between adjacent protruding electrodes contains no air bubbles, connection reliability and excellent moisture resistance is ensured.
