Abstract: In a magnet, an insulating layer is fixed to an upper surface of the magnet provided with the insulating layer, but is not fixed to a lower surface of the magnet above the insulating layer. Therefore, even when the magnet expands or contracts due to a temperature change, stress is less likely to occur at an interface between the insulating layer provided on the upper surface of the magnet and the magnet above the insulating layer.
