Abstract
To provide a magnetic sensor capable of detecting a weak magnetic field at a position situated apart from a magnetic field source. A magnetic sensor includes magnetic bodies whose magnetic collecting surfaces face mutually opposite sides and a magnetic detecting partthat detects magnetic flux passing between the magnetic bodies. With this configuration, magnetic flux collected from one magnetic collecting surface of one magnetic body passes to another magnetic collecting surface of another magnetic body through the magnetic detecting part, thereby making it possible to efficiently collect a magnetic field spreading in a space. Thus, even when a distance from a magnetic field source is large, magnetic collection can be achieved with high uniformity of a magnetic field.
