Abstract
Provided is a magnetic sensor testing device capable of preventing performance of an electromagnet from greatly changing due to heat applied to a magnetic sensor. A magnetic sensor testing device includes electromagnetsandthat apply a magnetic field to a magnetic sensor, temperature regulatorsandthat regulate a temperature of the magnetic sensor by locally applying heat to the magnetic sensor, and a controller that controls the electromagnetsandand the temperature regulatorsand, in which the controller tests the magnetic sensor in a state in which the magnetic field is applied to the magnetic sensor by the electromagnetsandwhile the heat is applied to the magnetic sensor by the temperature regulatorsand
