Patent ID: 8872039

Claim:
A conductive element comprising: a base having a first wavy surface, a second wavy surface, and a third wavy surface; a first layer provided on the first wavy surface; and a second layer provided on the second wavy surface, wherein the first layer has a multilayer structure in which two or more sublayers are stacked, the second layer has a single-layer or multilayer structure including part of the sublayers constituting the first layer, the first layer and the second layer form a conductive pattern portion, and the first wavy surface, the second wavy surface, and the third wavy surface satisfy the following relationship: 0≦(Am1/λm1)<(Am2/λm2)<(Am3/λm3)≦1.8 where Am 1 is a mean amplitude of vibrations of the first wavy surface, Am 2 is a mean amplitude of vibrations of the second wavy surface, Am 3 is a mean amplitude of vibrations of the third wavy surface, λm 1 is a mean wavelength of the first wavy surface, λm 2 is a mean wavelength of the second wavy surface, and λm 3 is a mean wavelength of the third wavy surface.
