A sheet-like conductor that is arranged on a display screen includes at least an insulator, a first detection electrode that is placed on a surface of the insulator on an opposite side to the display screen and arranged on a viewing side, and a second detection electrode that is placed on a surface of the insulator on a side close to the display screen and arranged on an opposite side to the viewing side, in which the first detection electrode and the second detection electrode are formed of thin metal wires in a mesh shape, and when a line width of the thin metal wire of the first detection electrode is a line width Wa and a line width of the thin metal wire of the second detection electrode is a line width Wb, the line width Wa and the line width Wb satisfy the following expressions (1) and (2). 0.5 μm≤Wb
