Abstract
A canned product heating apparatus includes: a non-contact type temperature detecting element which is not in contact with a surface of a can container; a directional microphone oriented to a closure of the can container; an interrupting circuit which interrupts an electrical supply to a high-frequency induction heating coil based on a signal transmitted from the directional microphone. The electrical supply to the high-frequency induction heating coil is stopped by the interrupting circuit in case the directional microphone captures sonic waves within a predetermined range.
