特徴とする光フアイバセンサ。 In an optical fiber sensor that detects an object to be inspected, such as paper, moving on a base plate by exposing the tips of a pair of optical fibers to a through hole in a base plate, the light emitting side optical fibers connected to the sensor body and a light-receiving side optical fiber, a cap for fixing the detection-side ends of both optical fibers, and a cylindrical collar attached to the tip of the cap and having a tip opening surface inclined with respect to the optical axis of the both optical fibers; It consists of a transparent glass plate attached to the slanted opening surface of the cylindrical collar, and this transparent glass plate portion is visible through the through hole of the base plate, so that the surface of this base plate and the surface of the transparent glass plate are on the same plane. An optical fiber sensor characterized by being set as follows.
