。[Claims for Utility Model Registration] 1. In a rotation angle detection device in which magnetoresistive elements are arranged in the rotating magnetic field of a permanent magnet attached to a rotating body, the patterns corresponding to the magnetoresistive elements are tilted by 45 degrees. A rotation angle detection device characterized in that it is configured with two sets of orthogonal patterns that are arranged at the same angle and that produce sinusoidal outputs of ten wavelengths different from each other in response to the rotating magnetic field. 2. The rotation angle detection device according to claim 1, which is characterized by comprising an electric circuit that performs arithmetic processing on the two sine wave outputs having ten different wavelengths for each region of the ten wavelengths.
