An object of the present invention is to provide a brushless motor and a wiper apparatus which allow high-precision control of a motor unit, and which can be reduced in size and weight. The first surface (91) of the control board (90) is provided on the same side as the rotating shaft (46) and the output shaft (51) so as to face the sensor magnet (MG1), the first and second Hall ICs (94a) and (94b) are mounted on the first surface (91). The second surface (92) of the control board (90) is provided on the opposite side from the first surface (91), and the third Hall IC (94c) is mounted on the second surface (92), and located between the first and second Hall ICs (94a) and (94b) so as to face the sensor magnet (MG1). In addition, the MR sensor (95) is mounted on the first surface (91) so as to face the second sensor magnet (MG2).
