Patent ID: 7352943

Claim:
An optical position sensing component comprising: an input light guiding portion constituted by a polymer first waveguide for inputting a light emitted from a near-infrared light-emitting source and outputting the light to a plurality of lenses for collimate through a plurality of ends; and a received light guiding portion constituted by a plurality of polymer second waveguides for inputting the light output from the input light guiding portion and outputting the input light to a near-infrared light-receiving device, wherein the polymer first waveguide and polymer second waveguides have a core portion composed of a cured photosensitive resin composition, the photosensitive resin composition including (A) an adduct of a copolymer containing at least a hydroxyalkyl (meth) acrylate and a (meth) acrylic acid as a monomer, and an isocyanate compound containing at least one (meth) acryloxy group in a molecule; (B) a compound containing at least one ethylene unsaturated group in a molecule (excluding (A) components); and (C) a photopolymerization initiator.
