PROBLEM TO BE SOLVED: To solve a problem wherein, since the position of an antenna is close to that of food in a conventional cooker for heating the food by radiating microwaves from the lower part of the food via the antenna, heating irregularity may be generated. SOLUTION: This high-frequency cooker is provided with: an antenna driving part 17 for stopping the antenna 16 at a first position for radiating the microwaves from at least a specific position of the antenna 16 and at a second position for radiating the microwaves from the circumference of the antenna 16 by vertically moving the antenna 16 disposed in a lower part of a food mounting surface 11 of a heating chamber 7; an infrared sensor 18 for detecting the temperature of the food; and a control part for controlling a magnetron 15 and the driving part 17 to execute cooking. The control part is so structured as to determine the position of the antenna 16 according the detected temperature by the infrared sensor 18 in the cooking start to move it to the first position or the second position by directing the driving part 17.
