The application provides a magnetic sensor which can suppress an irregularity of a central potential due to a change in a temperature, decrease size of the sensor, and lower the manufacturing cost of the sensor. A magneto-resistive element and fixed resister are provided on an element base and have the same configuration elements. A second magnetic layer and non-magnetic layer in the fixed resistor are reversely laminated on each other in a manner different from the magneto-resistive element, and the second magnetic layer is formed in contact with the first magnetic layer, thereby fixing the magnetization directions of the first magnetic layer and the second magnetic layer in the same direction. In this manner, the irregularity of the temperature coefficient between the magneto-resistive element and the fixed resistor is suppressed, and the irregularity of the central potential due to the change in the temperature is suppressed.
