Abstract
A hole is formed in a substrate of a magnetic detection device, the hole being spaced away from an outer edge of the substrate. Magnetic detection elements of a magnetic sensor detects magnetic field formed at first and second collector portions. A mold section encapsulates the magnetic detection elements. The magnetic sensor is surface mounted such that a portion of the mold section overlaps with the hole. The first collector portion faces a front surface of the magnetic sensor. A portion of the second collector portion is positioned in the hole to face a rear surface of the magnetic sensor. Accordingly, compared to a case where a hole is not provided, a magnetic circuit gap between the first and second collector portions is reduced.
