A liquid-cooling termination structure having temperature sensing function is disposed on a liquid-cooling system which is used for performing a heat dissipating operation to a heat source of equipment. The liquid-cooling termination structure includes a water cooling head and a temperature sensing unit. The water cooling head is formed with an adhering surface used for being adhered on the heat source. The temperature sensing unit includes a sensing terminal, and a signal transferring cable extended from the sensing terminal. The sensing terminal is combined with the water cooling head from the exterior of the water cooling head, and the signal transferring cable is connected to the equipment for obtaining the temperature of the heat source through the water cooling head.
