PURPOSE: To provide a position inputting device in which the input or detection of a position can be precisely attained with high resolution, and durability can be excellent.
CONSTITUTION: This device is provided with an optical waveguide member 1 which is equipped with an optical waveguide 2, optical path converting part 5 provided at the optical waveguide member 1 which converts the optical path of a light waveguided in the optical waveguide 2 outside the optical waveguide member 1, position inputting means 9 which is equipped with at least one of a light emitting means 10 arranged at one end face 4 side of the optical waveguide 2 which emits a light waveguided in the optical waveguide 2 and a light receiving means arranged at the other end face 4 side of the optical waveguide 2 which receives a light, and at least one of a light receiving means corresponding to the light emitting means arranged at one end face side of the optical waveguide and a light receiving means corresponding to the light emitting means arranged at the other end face side of the optical waveguide, and which is provided so as to be freely movable to the optical path converting part 5, and arithmetic means 7 which calculates the position of the position inputting means based on a light received by the light receiving means.
