PURPOSE: A golf club capable of correcting a golf putting/swing posture is provided to acquire a right golf putting or swing posture. CONSTITUTION: The golf club comprises: piezoelectric sensors(18a,18b,18c,18d) mounted in the head of the golf club by which a golf ball is stroked; peak holding circuits(22a,22b,22c,22d) sensing the peak values of an electric pulse corresponding to the impulse applied to the respective piezoelectric sensors(18a,18b,18c,18d), the impulse being determined by the stroke of the golf ball applied to the head; comparer(24a,24b,24c,24d) calculating the sum and difference of the peak sizes of the pulse while comparing the size of the peak of the electric pulse generated from the two piezoelectric sensors by pair; a micro-controller unit(28) calculating the stroke position of the head front surface, the angle between the golf ball and the head front surface and the traveling distance of the golf ball; and a display section(30) for displaying the output of the micro-controller unit(28).
