Manipulated position detection device

A manipulated position detection device comprising:

• a manipulated body including a manipulated surface portion substantially being in a plate shape;
• a case accommodating the manipulated body;
• a distortion member being in a plate shape, the distortion member having a joint portion connected with a periphery of the manipulated surface portion at one end, the distortion member further having a fixed portion fixed to the case at an other end, the distortion member having a movement transmission surface between the joint portion and the fixed portion, the movement transmission surface being movable according to a manipulating force caused by pressure applied to the manipulated surface portion;
• a distortion detection unit adhered to the movement transmission surface of the distortion member and configured to detect a distortion of the movement transmission surface caused by a movement of the distortion member;
• and
• a manipulated position arithmetic unit configured to calculate a manipulating force working on the manipulated surface portion and a manipulated position on which a manipulating force works, according to a detection result of the distortion detection unit, wherein
• the manipulated surface portion and all the movement transmission surface are located on a same plane.
