Beschreibung
Zusammenfassung:	A position calculation device calculates a position of a magnet installed on a moving body that is capable of moving relatively in a first direction. The position calculation device includes a first magnetic sensor and a second magnetic sensor arranged apart from each other by a predetermined distance in the first direction, and a calculation circuit that calculates the position of the magnet, using a first ratio between a first component in the first direction and a second component in a second direction, of a first magnetic flux density detected by the first magnetic sensor, a second ratio between a third component in the first direction and a fourth component in the second direction, of a second magnetic flux density detected by the second magnetic sensor, and the predetermined distance.
