Abstract:
A Z detection unit includes magnetoresistive elements provided on inclined side surfaces of Z detection recesses. An X detection unit includes magnetoresistive elements provided on inclined side surfaces of X detection recesses. A Y detection unit includes magnetoresistive elements provided on inclined side surfaces of Y detection recesses. Directions of fixed magnetization of fixed magnetic layers included in the magnetoresistive elements are set to directions shown by arrows with solid lines.
