Abstract
A high frequency bar type heater can be inserted into a hole of an object to be heated even if there is an obstruction above the hole. The high frequency bar type heater has a flexible and slender heat resisting and insulating tube (2) having both its ends closed so as to form a water-tight container. A flexible and slender conductor coil (3) is inserted in the heat resisting and insulating tube (2). A magnetic core (5), sectioned in plural pieces in its longitudinal direction, is contained on an inner side of the conductor coil (3). A flexible cooling water pipe (6) is inserted in the heat resisting and insulating tube (2) so as to cool the interior thereof. The high frequency bar type heater thus has flexibility as a whole. The magnetic core may also be formed of a flexible material.
