PURPOSE:To prevent the variation of offset voltage due to a humidity change by forming two ferromagnetic films having an anisotropic magnetoresistance effect so as to mutually cross at right angles on a substrate. CONSTITUTION:The magnetoelectric transducer 1 is formed by the folded line- shaped ferromagntic substances A, B, which are formed by evaporating a 80Ni- 20Co alloy to the insulating substrate 7, such as slide glass, a photographic dry plate or the like, to which interface purging treatment is executed, in the thickness of 600-1,000Angstrom and removing unnecessary sections through etching, an output terminal 4 shaped to the approximately intermediate position of the ferromagnetic substances A, B, and current terminals 2, 3 formed at other end sides of the ferromagnetic substances A, B. The ferromagnetic substances A, B consist of rectilinear sections 8, 9 functioning as main current paths and bent sections 10, 11 mutually connecting the rectilinear sections, and the rectilinear sections 8, 9 are mutually crossed at right angles. |
