To provide a golf score management system capable of grasping a game progress situation and placing in real time and reducing costs expended for the system.

A golf score management system is constructed in such a manner that communication terminals are provided in carts 20a to 20c, and a host system 10 repeats the receiving of score data by sending receiving permission instruction to all the carts for each specified time. Thus, since it is not necessary to provided a communication terminal to each player, the number of communication terminals to be used is reduced, maintenance is facilitated, costs are reduced, and the progress situation of a game and placing are grasped in real time. Also, by providing the communication terminal in the cart 20, low costs are realized for the communication terminal itself compared with the conventional case.
