Abstract:
A method for manufacturing a multiple optical path array type probe in which in a light guiding material including a substrate that functions as a clad and a light guiding path formed of a component that functions as a core for guiding light or as a waveguide,wherein the light guiding material includes a plurality of light guiding paths aligned to be parallel to each other within the single substrate that functions as a clad, and wherein the light guiding material is arranged so that a light transmittance preventing means is provided between the respective optical paths so that light is prevented from being transmitted between the respective optical paths, wherein tip end portions of the light guiding paths are sharpened through chemical etching of an end surface that is orthogonal to the plurality of light guiding paths, and wherein mask of a light blocking material and apertures are formed at tip end portion of the sharpened light guiding paths.
