Abstract
A conductive Sheet, a method for using conductive sheet, and a capacitive touch panel are provided. A first conductive sheet contains two or more conductive first large lattices and a first connection for electrically connecting the adjacent first large lattices on a first transparent substrate. The first large lattices each contain a combination of two or more small lattices, the first connection contains one or more medium lattices (a first medium lattice to a fourth medium lattice), and the pitch of the medium lattices is n times larger than that of the small lattices (in which n is a real number larger than 1).
