To provide a probe for optical measurement capable of reducing a diameter while preventing disconnection of an optical fiber.SOLUTION: A probe 10 for optical measurement comprises: an optical fiber 11; a ferrule 12 into which an optical fiber 11 is inserted so as to make one end of the optical fiber 11 exposed from one end thereof and make the other end side of the optical fiber 11 exposed also from the other end thereof; a non-flexible tubular body sleeve 13 into which at least a portion of the other end side of the ferrule 12 is inserted and which also covers a portion of the other end side of the optical fiber 11; and an optical fiber fixing part 14 that is composed of a material formed by solidifying a fluid material which is filled into a clearance between the optical fiber 11 and the body sleeve 13.SELECTED DRAWING: Figure 1 【課題】光ファイバの断線を防止しつつ径を小さくすることができる光学測定用プローブを提供する。【解決手段】光学測定用プローブ１０は、光ファイバ１１と、一端から光ファイバ１１の一端が露出し、他端からも光ファイバ１１の他端側が露出するように光ファイバ１１が内挿されているフェルール１２と、フェルール１２の少なくとも前記他端側の一部が内挿されていると共に、光ファイバ１１の前記他端側の一部を覆う、非可撓性の筒状の胴体スリーブ１３と、光ファイバ１１と胴体スリーブ１３の隙間に充填されている、流動性を有する材料が固化したものから成る光ファイバ固定部１４とを備える。【選択図】図１
