摘要： 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.

摘要： The magneto-sensitive wire of the invention has a vortex-spin structure and hence includes no magnetic domain walls, so that the magneto-sensitive wire of the invention has an excellent hysteresis characteristic exhibiting nearly zero hysteresis. Therefore, the linearity related to the output voltage characteristic for the applied magnetic field in the determination range of an MI sensor is significantly improved as compared to MI sensors using the conventional magneto-sensitive wires. Using the magneto-sensitive wire of the invention makes it possible to provide a magneto-impedance (MI) element exhibiting a higher precision than the conventional ones and further provide a sensor using such an MI element.
