To highly efficiently heat foods placed in two heights.
A wave guide 4 is attached ranging over upper and lower parts of a rack 8 for an oven rectangular pan in an outside of a heating chamber to propagate high frequency energy vertically, an upper feed port 6 and lower feed port 7 are provided in the upper and lower parts of the rack 8, a magnetron antenna A is attached to neighbor and face to a rack side opening edge part E of the lower feed port 7 out of them 6, 7, plural radial slot antennas are provided in a turn table 11, a ceramic pan 14 is mounted on it, at least three U-shaped legs are provided thereon to make a food mounting face 110 equal to the height of the rack in a heating chamber sidewall, the legs are formed in a set together with an annular trimming wire, plural parallel line antennas are formed in the food mounting face 110, and a mounting net 15 where the respective legs are connected to one of the line antennas in a connecting part with a wire material to form the right angled parallel line antennas is arranged. Heated foods divided into two stages to be mounted on the ceramic pan 14 and the net 15 are thereby heated uniformly and highly efficiently to be cooked.
