Abstract:
Provided is an anisotropic conductive sheet (8) having heat resistance and cold resistance and suitable for connection of electrodes. The anisotropic conductive sheet of the present invention has conductivity in the thickness direction, wherein the base film (1), which is a film made of synthetic resin having an electrical insulation property, has a plurality of holes (3) formed in the thickness direction, and the holes (3) are open to one main surface of the base film and closed to the other main surface, wherein a metal is adhered to the closed parts (2a) and the inner walls (2b) of the holes (3) so that by contacting electrodes (7) with the closed parts (2a) respectively from the outside, the electrodes (7) can electrically be connected through the adhered metal to the main surface where the holes (3) are open.
