PROBLEM TO BE SOLVED: To simplify assembling, removal and positional regulation for an optical fiber, to enhance a heat exhausting property, to reduce the number of component items, and to reduce a cost. SOLUTION: This sensor uses the optical fiber 29 with projection and photoreception axes coaxial each other having a small-diametric fiber part 29-1 and a large-diametric fiber part 29-2. A heat conductor 27 is constituted of integrated structure of the optical fiber 29 and a holding part 27n. The holding part 27n is constituted of a through hole 27f, a communication hole 27g, a wall (boundary face between the through hole 27f and the communication hole 27g) 27h, and a screw hole 27i. When assembling the optical fiber 29, the small-diametric fiber part 29-1 is inserted from a rear side of the communication hole 27g, the inserted small-diametric fiber part 29-1 is penetratedly inserted into the through hole 27f, the large-diametric fiber part 29-2 is positioned in the communication hole 27g, and a screw 30 set in the screw hole 27i is tightened from an outside of the heat conductor 27.
