Abstract:
A high-frequency induction heating device (20) that generates a magnetic field from a coil (24) by passing an alternating current (i) to the coil (24), which is arranged so as to be separated from an outer housing (11), is provided. By passing a current (i) having a predetermined frequency from the high-frequency induction heating device (20) to the coil (24), a ball part (10b) is induction-heated by the magnetic field generated by the coil (24) through which the current (i) is passed, and, after the ball part (10b) is brought, by induction heating, to a temperature at which a ball sheet (12) can be deformed, the current (i) is stopped and the ball part (10b) is cooled.
