PROBLEM TO BE SOLVED: To provide a swing practicing device optimum for the increase of the accuracy in swing and the swing speed. SOLUTION: A plurality of touch-sensing contact points for sensing a ball are disposed on a face part of a ball-hitting swing implement, and a touch sensor for processing signals from the touch-sensing contact points is disposed in a grip portion of the swing implement. When a spherical body is hit by the swing implement, the place of the face part where the spherical body is hit is sensed by the touch sensor. The sensed data are processed and recorded or displayed. In addition, a signal transmitting contact point and a signal receiving contact point are disposed in a swing speed measuring part of the swing implement, and a speed processing device to be connected to the respective contact points is disposed in the grip portion. The speed processing device transmits electromagnetic waves from the signal transmitting contact point and receives the reflected waves from the electromagnetic waves at the signal receiving contact point to compute the swing speed, and processes and records or displays the computed data.
