英文摘要	PURPOSE:To maintain at constant value the clearance between the light emitting part and the light receiving plane of an element to be tested and improve the reproducibility of the test, by projecting the fringe part of the optical fiber end part from the central part, and providing an abrasion resistant member on the fringe part. CONSTITUTION:An outer coating material 9 is formed around the optical fiber with a clad part 8, and a metallic sheath material 11 is constituted outside. The end part 11' of said metallic sheath material 11 has a conical aperture part, and on the top end a thin disc 13 which has a through hole 12 at the center and is constituted of Al2O3 crystal such as sapphire or of a material excellent in abrasion resistance such as a super steel alloy is fixed in a structure of slight projection from the top end part of the sheath material 11 by fitting or adhesion. The part contacted on the surface of the light emitting element to be tested is constituted of a material high in abrasion resistance, and the abrasion of the contacted part is not generated against repeated probings resulting in the prevention of damages of the light receiving part of an optical fiber. Since the clearance between the light receiving part and the contacted part is constantly maintained, the improvement of the reproducibility of the light receiving characteristic during probing can be realized.
