Claim 19:
20. A current detection apparatus comprising:
a plurality of magnetoresistive effect elements; and
a coil including a first tier part and a second tier part opposed to each other in a first axis direction, with the magnetoresistive effect elements being interposed between the first tier part and the second tier part, the coil being configured to be supplied with a current and thereby configured to generate an induction magnetic field to be applied to the magnetoresistive effect elements in a second axis direction, and
a conductive line configured to be supplied with a second current and thereby configured to generate a second induction magnetic field to be applied to the magnetoresistive effect elements in the second axis direction, wherein
the first tier part includes a plurality of first conductors each extending in a third axis direction that is along a winding direction of the coil, the plurality of first conductors being arranged in the second axis direction and coupled in parallel to each other,
the second tier part includes a second conductor extending in the third axis direction or a plurality of the second conductors each extending in the third axis direction, the plurality of second conductors being arranged in the second axis direction and coupled in parallel to each other, and
each of the magnetoresistive effect elements includes a plurality of magnetoresistive effect films arranged in the third axis direction.
