An electroconductive element includes a substrate having a first wavy surface and a second wavy surface, and an electroconductive layer formed on the first wavy surface, wherein the electroconductive layer forms an electroconductive pattern, and the first wavy surface and the second wavy surface satisfy the following relationship: 0≦(Am1/λm1)<(Am2/λm2)≦1.8. Am1 is a mean amplitude of vibrations of the first wavy surface, Am 2 is a mean amplitude of vibrations of the second wavy surface, λm1 is a mean wavelength of the first wavy surface, and λm2 is a mean wavelength of the second wavy surface. |
