Abstract
A magnetic field detection apparatus includes a magnetoresistive effect element and a conductor. The magnetoresistive effect element includes a magnetoresistive effect film extending in a first axis direction and including a first end part, a second end part, and an intermediate part between the first and second end parts. The conductor includes a first part and a second part that each extend in a second axis direction inclined with respect to the first axis direction. The conductor 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 a third axis direction orthogonal to the second axis direction. The first part and the second part respectively overlap the first end part and the second end part in a fourth axis direction orthogonal to both of the second axis direction and the third axis direction.
