摘要： PROBLEM TO BE SOLVED: To obtain an optical-fiber magnetic field sensor whose sensor sensitivity can be enhanced by separating the optical fiber guide of a sensing part in an optical fiber from the optical fiber guide of a reference part. SOLUTION: In this magnetic field sensor, a permanent magnet 4 is installed in advance between both ferrite magnetostrictive vibrators 1, and a magnetic field is applied to the inside of the ferrite magnetostrictive vibrators 1. When it is subjected to the magnetic field from the outside, the ferrite magnetostrictive vibrator 1 on one side is expanded, and the ferrite magnetostrictive vibrators 1 on the other side is contracted. Consequently, when optical fibers 6 are bonded to the ferrite magnetostrictive vibrator 1, the optical fibers 6 are expanded and contracted. The phase of light which passes the inside of the optical fibers 6 is changed, and the magnetic field can be detected. In this case, when the guide part 2 of a sensing part and the guide part 2 of a reference part are separated into a guide 2A and a guide 2B, the sensing part and the reference part are deformed independently. Consequently, it is possible to prevent the degradation of the sensor sensitivity of the magnetic field sensor. In addition, the optical fiber of the sensing part and that of the reference part are expanded and contracted in opposite directions, and the sensor sensitivity can be doubled.
