磁場検出装置および電流検出装置

Japanese Patent JP7024810

B2

A magnetic field detection apparatus includes a magnetoresistive effect element and a helical coil. The magnetoresistive effect element includes a magnetoresistive effect film extending in a first axis direction. The helical coil includes a parallel connection including first and second parts extending in a second axis direction inclined with respect to the first axis direction. The first and second parts are adjacent to each other in a third axis direction and coupled to each other in parallel. The helical coil is wound around the magnetoresistive effect element while extending along the third axis direction. The magnetoresistive effect film overlaps the first and second parts in a fourth axis direction orthogonal to the second and third axis directions. The helical coil is configured to be supplied with a current and thereby configured to generate an induction magnetic field to be applied to the magnetoresistive effect film in the third axis direction.
