Abstract
A magnetic field sensor fabrication method of directly forming, with an aerosol deposition method, at a tip of an optical fiber, a magnetooptical layer having a refractive index that changes depending on a magnetic field, the method includes establishing a relationship of dc≦d≦dr among a diameter d of the magnetooptical layer, a diameter dc of a core of the optical fiber, and a diameter dr of a clad thereof.
