Abstract
A magnetic sensor device includes three magnetic sensors for detecting components of an external magnetic field that are in three directions, a magnetic field generation section, and a correction processor. The magnetic field generation section generates additional magnetic field components in three directions used for measurements of main- and cross-axis sensitivities of the three magnetic sensors. The correction processor corrects respective detection signals of the three magnetic sensors on the basis of the measurement results of the main- and cross-axis sensitivities of the magnetic sensors.
