To provide a ball dispenser for a Pachinko game machine that smoothly dispenses game balls even when the game balls are dispensed in a short time by rotating a ball feeding member at a high speed, while reducing the size of the device.

The ball dispenser includes: a housing member 51 with a guide passage 55 for guiding downward the game ball flowing from a receiving port 52 at the upper end, to a dispensing port 53 at the lower end; the ball feeding member 60 rotatably provided in an intermediate position of the guide passage 55 in the housing member 51 and delivering the game ball flowing from the receiving port 52 by the rotation toward the dispensing port 53; and a ball dispensing motor for rotationally driving the ball feeding member 60. The guide passage 55 is formed obliquely to a vertical direction so that the direction of supplying the balls to the ball feeding member 60 in the intermediate position is along the rotating tangential direction of the ball feeding member 60.
