Abstract
A conductive sheet, method for using conductive sheet and touch panel, having a base substance and conductive parts formed on one of the principal surfaces of the base substance. The conductive parts respectively extend in primary directions, and have two or more conductive patterns made from metal wires arranged in a second direction that is perpendicular to the first direction. The conductive pattern is constituted by serially connecting two or more large gratings in the first direction, and each of the large gratings is constituted by combining two or more small gratings. Around the edges of the large grating, non-connective patterns are formed from metal wires which are not connected with the large gratings.
