To provide a table tennis serve training device enabling a user to improve his or her serving ability.SOLUTION: A table tennis serve training device includes: a table tennis table formed by a first part where first bound of a table tennis ball with a net in between occurs and a second part where second bound is occurs beyond the net; a plurality of serve position sensor parts which are provided at mutually different positions of the second part, provided with sensing sensors, and are formed so as to sense a position of the second bound caused by the table tennis ball through vibration sensing; light emission parts which are provided for the serve position sensor parts and formed in the way that mutually different colors are emitted outside the serve position sensor parts in accordance with setting states; and a terminal unit which is provided in the way that it can perform wireless communication with the serve position sensor parts and provides a first signal for activating the sensing sensors to the serve position sensor parts in the state that position sensing is possible. The serve position sensor parts transmit to the terminal unit a second signal when vibration is sensed by the sensing sensors.SELECTED DRAWING: Figure 1
