Abstract: Provided is an optical sensing member, comprising a light guide plate 102 which propagates light from a light source unit 108, detecting units 104, 106 which detect scattered light from the light guide plate 102 being touched, an optical member which guides the scattered light to the detecting units, and a primary control unit 118 which computes the touch location upon the light guide plate 102 on the basis of information relating to the detected light. The optical member has arc-shaped curved surfaces formed on the end parts which face each of the detecting units. Each of the detecting units outputs, as the information relating to the light which is detected by the detecting units, location information corresponding to the angle of entry to the detecting units of the light which is radiated from the facing arc-shaped curved surfaces. It is thus possible to clarify contours of the light which is detected by the detecting units, and to improve the precision of the detection of the touch location.
