Abstract
There is provided a magnetic detection device including: a substrate including: a hole portion into which a magnet is inserted from a side of one main surface; and a stopper for stopping, from a side of another main surface, the magnet inserted into the hole portion to prevent the magnet from protruding toward the side of the another main surface; and a magnetic sensor mounted at a position corresponding to the hole portion, in the another main surface. The substrate may include a first substrate, and a second substrate bonded to the first substrate from the side of the another main surface. The hole portion may be a first through hole formed in the first substrate. The stopper may include a region, in the second substrate, that closes the first through hole.
