The purpose of the present invention is to provide a sensor device that can obtain stable sensing precision even if an environmental temperature changes. A magnetic sensor device (10) (sensor device) comprises: a circuit board (50); a magnetic sensor (3) (sensor) mounted on the circuit board (50); and a microcomputer (91) (first electronic component) mounted on the circuit board (50). The magnetic sensor (3) has a resistive membrane for monitoring temperature (temperature sensing part) and a resistive membrane for heating (heater) formed thereon. The resistive membrane for heating heats a magnetic resistance component maintaining the temperature of the magnetic resistance component used for the magnetic sensor (3). The circuit board (50) has slits (52, 53) formed around the magnetic sensor (3) except for part of the circuit board (50). The slits (53) extend in a direction intersecting with a virtual line for connecting the magnetic sensor (3) to the microcomputer (91). |
