    • PROBLEM TO BE SOLVED: To provide a high-frequency heating device capable of efficiently heating a heated object. SOLUTION: This high-frequency heating device includes a weight detecting means 5 for measuring a weight of the heated object 20, a rotary antenna 10 disposed on an upper end section of an antenna post 14, a driving motor 11 connected to a lower end section of the antenna post 14 through a dielectric shaft 12 having a projection 12a in the circumferential direction, a position detector 15 for detecting a position of the projection 12a, and a control means 9 for controlling the driving motor 11 on the basis of the information from the weight detecting means 5 and the position detector 15. In heating the heated object 20, the control means 9 allows the rotary antenna 10 to make a 360-degree turn first, then manages a stop position of the rotary antenna 10 based on a lapse time from the detection information of the position detector 15 according to the weight information of the weight detecting means 5, repeats rotation and stop several times during the 360-degree turn of the rotary antenna 10, and allows the rotary antenna 10 to continuously rotate until the heating is terminated, after the lapse of time when a temperature of the heated object 20 reaches 80% of a heating termination temperature.
