PROBLEM TO BE SOLVED: To provide a ball shooting device of a pachinko game machine capable of achieving stability of shooting balls. SOLUTION: Heat in an exciting coil 12 is discharged from a yoke 2 through a cooling fin 5, and an electric resistance value of the exciting coil 12 is less likely to change by the effect of heat, even if ball shooting operation is continued in an extended period of time. Thereby, a magnetic field formed by the exciting coil 12 is prevented from becoming weak, and the yoke 2 appropriately sucks a plunger 14.
