PURPOSE: A golf ball sensing device is provided to reduce the sensing errors generated by the detection of articles. CONSTITUTION: A golf ball sensing device comprises a first sensing part(112) which is extended in a first horizontal direction which first senses a golf ball, and a second sensing part(122) which is extended in parallel with the first sensing part that senses the golf ball. The sensing direction of the first sensing part has an acute angle in the first horizontal direction. The sensing sensitivity of the first sensing part is reduced in a direction that becomes distant from the user.
