PROBLEM TO BE SOLVED: To provide a high frequency heating device to facilitate assembly and perform accurate assembly of a door and a heating chamber. SOLUTION: The high frequency heating device comprises a heating chamber 4; a bottom plate 3 of a body below the heating chamber 4; a pair of hinge plates 8 mounted on the bottom plate 3; and a longitudinally opening door 2 to open an opening part 10 of the heating chamber 4 around a fulcrum hole 9, serving as a fulcrum, formed in the hinge plate 8. In the heating chamber 4, a front plate 5, a rear plate, a heating chamber body 6, and a heating chamber bottom plate 7 are joined together by a flange at the outside of the heating chamber 4 for integral constitution. By fitting a part of the hinge plate 8 in a slit formed in a flange-joint between the heating chamber body 6 and the heating chamber bottom plate 7, and relative longitudinal movement with the heating chamber 4 is regulated and a distance from the fulcrum hole 9 of the hinge plate 8 to the front plate 5 of the heating chamber is rendered constant. A gap between the heating chamber front plate 5 and the door 2 is rendered constant without using a fixture. Even when the front plate 5 of the heating chamber is warped, the gap can be rendered constant and mounting and demounting of the hinge plate 8 are facilitated.
