Abstract
Provided is a magnetic field detection device and a current sensor capable of increasing the degree of freedom in selecting the type of the magnetic field detection element. A magnetic field detection deviceincludes a conductorthat generates a magnetic field; a C coreprovided so as to surround the conductor; and a magnetic field detection elementthat detects a magnetic field. The C corehas a gap G, and the magnetic field detection elementis disposed at a position where the magnetic field generated from the conductorcan be detected, the position being outside the gap G. Since the direction of the magnetic flux varies outside of the gap Gfrom place to place, the direction of the magnetic flux that passes through the magnetic field detection elementcan be arbitrarily selected by arbitrarily selecting the installation location of the magnetic field detection element. Therefore, the degree of freedom in selecting the type of the magnetic field detection elementis increased.
