摘要：
A rotation angle sensor including: a magnet (10) fixed to an end (5) on an opposite side to an output end (4) of a rotation shaft (3) of a motor (2); a circuit board (11) on which a plurality of magnetic resistance sensor elements (20, 21) are mounted; and a support member (12) fixed to the motor (2), wherein the circuit board (11) is arranged between the support member (12) fixed to the motor (2) and the motor (2) and is fixed to the support member (12) in such a way that the plurality of magnetic resistance sensor elements (20, 21) come close to the magnet (10).
