Abstract

Official abstract text for this publication.

A conductive sheet 10 includes a peeling film 11 and a conductive film 12 . The conductive film 12 is formed on one surface of the peeling film 11 . The conductive film 12 is made of conductive composition. The conductive composition contains an elastomer and a dendrite-shaped conductive filler filled in the elastomer.

First claim

Opening claim text (preview).

1 . A conductive film comprising: an urethane-based elastomer; and a dendrite-shaped conductive filler filled in the urethane-based elastomer, wherein a filling factor of the conductive filler in the urethane-based elastomer is 70 weight % or more and 95 weight % or less. 2 . The conductive film according to claim 1 , wherein a filling factor of the conductive filler in the urethane-based elastomer is 70 weight % or more and 90 weight % or less. 3 . The conductive film according to claim 1 , wherein the conductive filler is a dendrite-shaped silver powder. 4 . The conductive film according to claim 1 , wherein the conductive filler is a silver-coated copper powder including a dendrite-shaped copper powder coated with silver. 5 . The conductive film according to claim 1 , wherein the conductive filler is a dendrite-shaped copper powder. 6 - 10 . (canceled) 11 . A conductive sheet comprising: a peeling film; and the conductive film according to claim 1 formed on one surface of the peeling film. 12 . A conductive sheet comprising: a peeling film; the conductive film according to claim 1 formed on one surface of the peeling film; and an insulating protective film formed on a surface of the conductive film, the surface being on the opposite side of the peeling film. 13 . The conductive film according to claim 2 , wherein the conductive filler is a dendrite-shaped silver powder. 14 . The conductive film according to claim 2 , wherein the conductive filler is a silver-coated copper powder including a dendrite-shaped copper powder coated with silver. 15 . The conductive film according to claim 2 , wherein the conductive filler is a dendrite-shaped copper powder. 16 . A conductive sheet comprising: a peeling film; and the conductive film according to claim 2 formed on one surface of the peeling film. 17 . A conductive sheet comprising: a peeling film; the conductive film according to claim 2 formed on one surface of the peeling film; and an insulating protective film formed on a surface of the conductive film, the surface being on the opposite side of the peeling film. 18 . The conductive film according to claim 1 , wherein a filling factor of the conductive filler in the elastomer is 70 weight % or more and 85 weight % or less.
