Abstract
A high-frequency heating apparatus according to an embodiment of the present disclosure includes a heating chamber, an electrode, a high-frequency power supply, at least one matching element, and a controller. The heating chamber accommodates a heating target. The high-frequency power supply applies a high-frequency voltage to the electrode. The impedance matcher includes at least one matching element having a matching constant that is variable. The controller stops the high-frequency power supply to complete heating based on a temporal change of the matching constant of the at least one matching element. In this embodiment, a heating target can be heated efficiently.
