Abstract
Provided is a magnetic field detection device capable of detecting with a higher accuracy. A magnetic field detection deviceincludes a first magnetic sensor unit, a second magnetic sensor unit, a third magnetic sensor unitand a fourth magnetic sensor unit. The first and the second magnetic sensor units are disposed side by side so that a sensitive axis directions of the first and the second magnetic sensor units are oriented in a first direction, and the third and the fourth magnetic sensor units are disposed side by side so that the sensitive axis directions of the third and the fourth magnetic sensor units are oriented in a second direction. The first and the second magnetic sensor units are disposed between planes each including a center of gravity of each of the third and the fourth magnetic sensor units and defining the second direction as a normal direction, and the third and the fourth magnetic sensor units are disposed between planes each including a center of gravity of each of the first and the second magnetic sensor units and defining the first direction as a normal direction.
