PROBLEM TO BE SOLVED: To provide a ball shooter of stable performance, in small size, capable of achieving excellent energy efficiency in spite of use of a clapper type electromagnetic solenoid (electromagnet), while making precision of each part, and assemblage precision moderate. SOLUTION: The ball shooter 1 includes a coil 4, the electromagnet provided with a stator 5 and a movable element 6, a hammer 7 provided on the movable element, and a shooting rail 9 for a ball stricken by the hammer. The stator is formed of an inner core 5a positioned at a coil inner diameter part, and an L-shaped outer core 5b continuously provided with the inner core to be disposed on one side of a coil outer diameter part, into C-shape. At one end part of the inner core, an attracting recess 17 is formed to which a projecting head 20 formed along the turning direction of the movable element can approach, as operational current to the electromagnet is fed.
