A magnetic detection device of the present invention includes at least one pair of first magnetosensitive bodies each comprising a soft magnetic material extending in a first axis direction and being sensitive to an external magnetic, field oriented in the first axis direction; and a magnetic field direction changer comprising a soft magnetic material and changing an external magnetic field oriented in a different axis direction from the first axis direction into a measurement magnetic field having a component in the first axis direction which can be detected by the at least one pair of first magnetosensitive bodies. With this magnetic detection device, the external magnetic field oriented in the different axis direction can be detected by way of the first magnetosensitive bodies. As a result, while attaining magnetic detection with high accuracy, the magnetic detection device can be reduced in size or thickness by omitting a magnetosensitive body extending long in the different axis direction. |
