A training putter comprises a game rod and a warning device. The game rod has a shaft of a hollow tubular body made of an elastic and electrically conductive material. The warning device comprises a conductive rod, a buzzer, and a battery. The conductive rod is a metal rod and is provided with one or more insulation members. The conductive rod is disposed in the shaft such that the conductive rod is not in contact with the shaft. The conductive rod has a contact portion capable of making contact with the inner wall of the shaft at the time when the shaft is curved. The buzzer and the battery are fastened with the game rod such that the buzzer, the battery, the conductive rod, and the shaft form a loop at such time when the shaft is curved.
