HIGH-FREQUENCY HEATING COIL

摘要

PROBLEM TO BE SOLVED: To provide a high-frequency heating coil capable of increasing cooling efficiency and strength, thereby capable of achieving a smaller diameter of a coil.SOLUTION: There is provided a high-frequency heating coil 2 in a high-frequency heating device for heating an object by induction heating. The coil is fabricated of a nonmagnetic good conductor and has a projecting part 7 formed on the inner face of the coil.
