摘要： PROBLEM TO BE SOLVED: To shorten the total length of a sensing fiber by winding the fiber around a conductor for carrying a measuring current, to make straight polarized light enter the fiber and to separate outgoing light into polarized components, and enclosing the fiber in a circulating groove of an annular frame body. SOLUTION: A sensing fiber 1 is wound around a conductor 4 being embedded in a circulating groove 7 formed at the axial end face 20 of an annular frame body 2. Incident light from a light source via an external fiber 10 becomes a straight polarized light at a polarizer part 21 via an optical connector 5 and an incoming fiber 15 and passes the fiber 1 to circulate around the conductor 4, and is separated into two orthogonal polarized light components at an analyzer part 12 and passes X, Y outgoing fibers 14a, 14b and travels toward an optical signal measuring device via the optical connector 5 and external fiber 10. The polarizer part 21 and analyzer part 12 are enclosed in recessed parts sufficiently deep from the height of their cases, and the depth of the circulating groove is also made sufficiently deep. The fiber 1 can therefore be prevented from bending in close proximity to the polarizer part 21 and analyzer part 12.
