To provide a golf ball stopper 1 set on a cart path R in the golf course, which does not prevent a cart for riding from passing and which can maintain an effect as a stopper for a long time.

This stopper has a net 2 across a cart path R, a post 3 with a pile shape on both sides of the cart path R to put up the net 2, and a coil spring 4 to connect the net 2 and the post 3. When the cart for riding passes through, the cart's wheels stamp down and climb over the net 2. After passing, the net 2 returns to its former state due to an elasticity of the coil spring 4. This net can be set up at low cost because of no need of specialized skill.
