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.

Optical position sensing component, optical position sensing device, and manufacturing method thereof

A radiation-curable composition containing (A) hydrolyzates of hydrolyzable silane compounds represented by general formula (1): (R)(R)Si(X)(wherein Ris a non-hydrolyzable organic group having 1 to 12 carbon atoms that contains fluorine atoms, Ris a non-hydrolyzable organic group having 1 to 12 carbon atoms (but excluding ones that contain fluorine atoms), X is a hydrolyzable group, p is an integer of 1 or 2, and q is an integer of 0 or 1) and condensates of such hydrolyzates, and (B) a photo acid generator, wherein the ratio of silanol (Si&#x2014;OH) groups in the composition is 0.1 to 0.5 out of all the bonding groups on Si. With such a composition, the waveguide loss is low for light having a wavelength in a broad range from the visible region to the near infrared region, and moreover the cracking resistance, the patterning ability upon irradiation with radiation, and so on are excellent.
