A rotation angle detecting apparatus (6) comprises a shaft portion space (4) formed in a rotation shaft (1) and a detection pattern (11) rotating with the rotation shaft, an image sensor (12) for acquiring images of the detection pattern, and an arithmetic unit (14) for calculating an angle displacement of the rotation shaft based on a signal from the image sensor. The detection pattern has an angle detection pattern (26) with radially extending bar-like line segments arranged at a predetermined angle pitch and forming a ring-like track, and a reference designation pattern (27) for indicating a reference position. The arithmetic unit carries out a total circumferential scanning on the ring-like track at a predetermined radius about a center of the angle detection pattern as the center in regard to a projection image of the detection pattern obtained by the image sensor, extracts a frequency component, carries out a scanning of the reference designation pattern, and calculates the angle displacement of the rotation shaft based on a phase difference of the frequency component and the number of frequencies corresponding to a change in a position of the reference designation pattern.
