PROBLEM TO BE SOLVED: To provide an apparatus for measuring golf club swing speed. SOLUTION: This apparatus for measuring golf club swing speed automatically indicates golf club swing speed by detecting a state where optical signals, such as infrared rays, outputted from a transmitting device thereof are blocked by a golf club. A receiving device of the swing speed measuring apparatus calculates the golf club swing speed by dividing a distance between the optical signals by a time interval taken between when the optical signals are blocked, and outputs the calculated swing speed. In particular, the transmitting and receiving devices are manufactured as separate devices. Because meaningless swing motion such as a case where a user slowly swings the golf club around the ball to take a proper stance or posture can be excluded and an actual swing motion can be distinguished accordingly, the motion is stable. Furthermore, in an embodiment wherein a swing tempo from user's back swing starting to a normal swinging is displayed easily understandable, it is useful for each user to find out a suitable timing.
