Abstract
An optical position sensing component includes an input light guiding portion and a received light guiding portion. The input light guiding portion is constituted by a polymer waveguide and inputs a light emitted from a near-infrared light-emitting source and outputs the light to a lens for collimate through a plurality of ends. The received light guiding portion is constituted by a polymer waveguide and inputs the light output from the light guiding portion and outputs the input light to a near-infrared light-receiving device. Further, the polymer waveguide has a core portion composed of a cured photosensitive resin composition.
