Summary:The objective of the present invention is to obtain a high-frequency heating device that is capable of propagating high-frequency waves, which have been oscillated by a high-frequency oscillator, into a heating chamber more evenly. An antenna (20) of the high-frequency heating device is equipped with: slot antennas (31, 32) that utilize slit apertures (31b, 32b), which are created on conductor sections (31a, 32a) connected to an antenna shaft (22), as first radiating sections (30); conduction paths (42, 43) that are bifurcated from the first radiating sections (30); and a second antenna that utilizes an antenna plate (41), which is connected to the conduction paths (42, 43), as a second radiating section (40). La présente invention vise à proposer un dispositif de chauffage à haute fréquence qui est apte à propager plus régulièrement dans une enceinte de chauffage des ondes à haute fréquence qui ont été produites par un oscillateur à haute fréquence. Une antenne (20) du dispositif de chauffage à haute fréquence comprend : des antennes à fentes (31, 32) qui utilisent, comme premières sections rayonnantes (30), des ouvertures en forme de fente (31b, 32b) qui sont créées dans des sections de conducteur (31a, 32a) connectées à une tige d'antenne (22) ; des trajets de conduction (42, 43) qui bifurquent par rapport aux premières sections rayonnantes (30) ; et une seconde antenne qui utilise, comme seconde section rayonnante (40), une plaque d'antenne (41) qui est connectée aux trajets de conduction (42, 43).
