Abstract
A motor includes a rotary shaft and a motor housing internally housing the rotary shaft. The motor housing is provided with a mounting hole in a position corresponding to an end of the rotary shaft. A detection rotor is fixed to the end of the rotary shaft. A detection stator includes a detection part made of resin into a plate-like shape having a surface on which a planar coil is placed, an outer peripheral wall axially extending from an outer circumferential edge of the detection part, and a flange radially extending from the outer peripheral wall. The detection stator is placed so that a surface of the detection part faces the detection rotor and the surface of the detection part faces to the inside of the motor housing in the mounting hole, and fixed to outside of the motor housing with a screw to the flange.
