Abstract: The present invention provides an optically transparent electrode being resistant to corrosion regardless of the shape of the pattern and enabling uniform electroless plating thereon regardless of the shape of the pattern. The optically transparent electrode has, on a support, an optically transparent electrode unit and a peripheral wire unit formed of at least one peripheral wire, of which one end is electrically connected with the optically transparent electrode unit and the other end is connected with the outside, and the optically transparent electrode unit and the peripheral wire unit are formed of the same metal. The line width of at least one metal wire forming the peripheral wire unit is not uniform, and when the at least one metal wire is divided into a thinnest metal wire segment A and the other metal wire segment B electrically connected with the metal wire segment A, the line width of the metal wire segment A is 1.

Abstract: Provided is an optically transparent conductive material which has low visibility and reduced occurrence of short circuit and therefore is suitable as an optically transparent electrode for projected capacitive touchscreens. The optically transparent conductive material has, on a base material, a sensor part composed of a metal pattern electrically connected to a terminal part and a dummy part composed of a metal pattern not electrically connected to the terminal part. When a line dividing the sensor part and the dummy part is referred to as an imaginary boundary line, the metal pattern of the sensor part and/or the metal pattern of the dummy part is displaced along the imaginary boundary line.
