<p><P>PROBLEM TO BE SOLVED: To provide a high frequency heating device capable of accurately and promptly sensing a temperature rise in a magnetron anode so as to prevent the thermal runaway and breakage of the magnetron and deformation of a resin component such as an air guide which are caused when a temperature sensor cannot accurately sense a temperature rise of the magnetron anode, capable of achieving stable quality and advantageous to resource saving. <P>SOLUTION: The temperature sensor 21 is arranged in the approximately center of a plurality of cooling fins 3B, and the lateral face 21A is pressed by the cooling fins 3B. The distal end 21B of the temperature sensor 21 is mounted toward the anode 3A side on the downwind side of a cooling fan 20. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
