PROBLEM TO BE SOLVED: To provide a tactile sensor having a small-sized device, capable of detecting accurately the pressure contact position of an object and the pressure, and detecting the pressure contact position and the pressure on both faces. SOLUTION: This tactile sensor is equipped with a light source 5, a transparent board 1 for guiding light emitted from the light source 5, and a plurality of movable members moved by action of an external pressure. The movable member has a tactile part 7 directly receiving the external pressure, a projection part 3 for transmitting light from the transparent board 1 and a light receiving part 4 for receiving light transmitted through the transparent board 1. The light receiving part 4 is provided between the tactile part 7 and the projection part 3. COPYRIGHT: (C)2004,JPO&NCIPI
