Abstract (en)
A high frequency heating device according to the present disclosure includes: a heating chamber having an opening on a front surface and accommodating an object to be heated; a high frequency wave generation unit that supplies high frequency waves to the heating chamber to heat the object to be heated; and a door that covers the opening in an openable manner and has a radio wave sealing portion at a position facing a peripheral edge surface of the opening. The radio wave sealing portion is provided with an open hole formed at a position facing the peripheral edge surface of the opening, and a choke groove curving toward the heating chamber with respect to the open hole. The choke groove is formed by bonding a plurality of conductors. The plurality of conductors includes a first conductor provided with a protrusion protruding to an inner side of the heating chamber near a bonding portion where the plurality of conductors is bonded. A backside space of the protrusion constitutes a part of the choke groove.
