PROBLEM TO BE SOLVED: To provide a ball supply tube for a pachinko machine hardly causing a ball jam and reducing a risk of breaking a bottom face in a ball tank. SOLUTION: This ball supply tube 1 for the pachinko machine is arranged vertically in the back face upper part of a game board for feeding a ball into the ball tank 3. In the ball supply tube 1, a ball guide part 7 is arranged in the terminal end part 6 on the inside side wall on the opposite side to the ball flow direction of the ball dropped in the ball tank 3 so that the ball is dropped diagonally to the ball flow direction, and consequently, the ball jam caused when the following ball is put on the previous ball can be prevented while a shock of the dropped ball is received to be reduced by the ball guide part 7. When a length of a terminal end part 8 in the ball supply tube side wall in the ball flow direction is set to be shorter than that of the terminal end part 6 in the side wall having the ball guide part 7 and a recess part 9 for relieving the ball is arranged in the terminal end part 8, the ball can be discharged smoothly.
