A position input device includes electrodes formed of metal with a belt-like shape, extended along a first direction, and arranged with a space therebetween along a second direction that is orthogonal to the first direction, lines each electrically connected to one end of each of the electrodes in the first direction to receive a signal, dummy electrodes formed of metal with a belt-like shape and each disposed in a space between the electrodes that are adjacent, and dummy lines each coupled to an end of each of the dummy electrodes in the first direction in an electrically disconnected state. The electrodes, the lines, the dummy electrodes, and the dummy lines each include a front side surface and a back side surface in a plane along the first direction and the second direction, and at least one of the front side surface and the back side surface is blackened.
