1. A magnetic field detection apparatus comprising:
a magnetoresistive effect element, and
a coil including a first tier pan and a second tier part opposed to each other in a first axis direction, with the magnetoresistive effect element 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 app lied to the magnetoresistive effect element in a second axis direction, wherein
the first tier part includes a plurality of first conductors each extending in a third axis direction, 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 plurality of 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
the plurality of first conductors is larger in number than the plurality of second conductors.
