A motor comprises a motor main body including a rotor and a stator around which a coil is wound, a drive circuit part including a circuit board to which a drive circuit including a power element is attached on mainly one face, a heat sink arranged on another face of the circuit board and to radiate heat of the drive circuit part, and a winding terminal to which at one side of the winding terminal an end portion of the coil of the motor main body is electrically connected. Another side of the winding terminal is partially electrically connected to the power element attached to the circuit board, and the winding terminal conducts heat generated by the power element from the one face to the other face of the circuit board.
