Abstract
A heating apparatus for heating a prepackaged food, is provided with a heater which heats a prepackaged food, an enclosure which defines an airtight chamber operable to accommodate the prepackaged food, and a pressure controller which controls the inside pressure of the airtight chamber. The heater includes a pair of electrodes which are arranged face to face, and an electric power source which supplies a high frequency electric power. The inside pressure of the airtight chamber is controlled in response to an expansion of the prepackaged food being heated to prevent the packaging container from breaking out.
