A magnetic sensor includes: a first magnetic detection element group G11 and a second magnetic detection element group G12 each of which including a plurality of self-pinned magnetoresistive effect elements; and a first control unit and a second control unit configured to respectively process detection signals detected from a magnetic field by the magnetoresistive effect elements M of the first magnetic detection element group G11 and the second magnetic detection element group G12, in which pinned magnetization directions (D1, D2, D3, and D4) of at least two magnetoresistive effect elements M in the first magnetic detection element group G11 and the second magnetic detection element group G12 are different from each other, and the plurality of magnetoresistive effect elements M of the first magnetic detection element group G11 and the plurality of magnetoresistive effect elements M of the second magnetic detection element group G12 are arranged so that the magnetization directions (D1, D2, D3, and D4) thereof are symmetrical. |
