摘要：
A magnetic sensor that prevents offset voltage from changing as time elapses. The magnetic sensor detects change in the direction of the magnetic field when the electric resistances of magnetic resistors change. The magnetic resistors of the magnetic sensor each include a heat treatment section formed by performing a pre-trimming heat treatment.
