摘要：
A touch panel includes: an infrared light transmitting material through which infrared light is transmitted and which has a surface as a touch surface (20) touched by a detection subject; area sensors (3) including photo sensor elements (4) below a touch region, which is touched by the detection subject, of the infrared light transmitting material; and infrared light sources (1) provided outside the touch region, the infrared light sources (1) emitting infrared light along said surface of the infrared light transmitting material such that an entire circumference of the detection subject touching the touch surface (20) is irradiated with the infrared light, the touch panel detecting a position touched by the detection subject so that the photo sensor element (4) receives, among infrared light emitted by the infrared light sources (1) along said surface, infrared light reflected by the detection subject and transmitted through the infrared light transmitting material.
