Abstract
A magnetic field detection device includes a magnetic field generation unit that generates a magnetic field, a magnetic field detection unit that detects the magnetic field, a first housing that has an accommodation unit that accommodates the magnetic field detection unit so that the magnetic field detection unit is exposed, and a second housing that movably accommodates a moving body. The strength or angle of the magnetic field generated from the magnetic field generation unit and applied to the magnetic field detection unit changes in accordance with movement of the moving body. The second housing has a mounting unit on which the first housing is mounted. The first housing is mounted on the mounting unit via a seal member that surrounds the magnetic field detection unit, so that the mounting unit is between the magnetic field detection unit and the moving body, and the inside of the accommodation unit is sealed by the seal member and the mounting unit.
