摘要： A high frequency heating coil is provided in which a main body part of a workpiece is surrounded by a loop part of the high frequency heating coil and subjected to high frequency heating, and a flange part of the workpiece is sandwiched by first and second lead-out parts of the high frequency heating coil and subjected to high frequency heating. The first and second lead-out parts oppose the flange part and are offset in the axial direction of the workpiece, thereby preventing eddy currents in opposite directions to each other from being generated in the flange part and preventing the flange part from being more difficult to heat than the main body part. The high frequency heating coil can uniformly heat a pipe-shaped workpiece having a flange part projecting radially outward from an outer peripheral face of a main body part.
