Abstract:
Provided is a magnetic field detection device in which the position of a magnetic sensor can be adjusted even after being attached to an existing device. The magnetic field detection device comprises: a lid body (110) that covers an opening (11A) of a housing (11) that has an opening and a space (11B) that communicates with the opening; a magnet (130) that is disposed inside the space and can rotate as seen in a plan view of the opening; and a magnetic sensor (150) that is disposed spaced away from the magnet at a magnet-facing position on the lid body, and detects changes in the magnetic field accompanying the rotation of the magnet. The lid body has a position adjustment section (112) that can move the magnetic sensor so that the facing distance (D) between the magnetic sensor and the magnet is changed.
