A coil so assembled as to be opposed to either a magnet (2) comprising a rin g body coaxial with a shaft (1) of an inner rotor at its center or a laminated yoke (3a) comprising a ring body coaxial with the shaft (1) of an outer roto r. A coil (9 or 90) for a small-sized motor is provided winding sections (4a, 4 b) facing a peripheral side face (2a) of the ring body (2 or 3a), winding sections (4c, 4d) facing both ring surfaces (2b, 2c), is formed as a hollow wound body in which the winding start ends and winding termination ends are connected continuously, and has a good efficiency of generation of torque. A high-torque small-sized flat motor and a vibration small-sized flat motor ar e constituted as a motor which is thin as a whole.
