The present invention relates to a magnetic sensor using a hall element which reduces magnetic offset in a circuit configured to reduce magnetic offset using a spinning current method. The magnetic sensor comprises: a switch to switch a current route connected to each terminal of the hall element to switch a route to a first current route and a second current route; a switch to switch an output route connected to each terminal of the hall element to switch a route, which outputs a hall voltage, to a first output route and a second output route; and a subtractor configured to output a difference of an output voltage of the first output voltage and an output voltage of the second output voltage. A wiring resistance value of the first output route is the same as a wiring resistance value of the second output route. |
