1. A magnetic field detection device comprising:
a first soft magnetic body and a second soft magnetic body that extend along a first plane and that are opposed to each other in a third direction, the first plane including a first direction and a second direction that is orthogonal to the first direction, the third direction being orthogonal to the first direction and the second direction;
a plurality of magnetic collection regions provided between the first soft magnetic body and the second soft magnetic body in the third direction;
a magnetic detector provided between the first soft magnetic body and the second soft magnetic body in the third direction; and
a lead provided so as to be connected to the magnetic detector and supply a sense current to the magnetic detector,
wherein the magnetic detector and the lead are respectively provided in areas without overlapping any of the plurality of magnetic collection regions in a direction along the first plane.
