Abstract
A refrigerator includes a cooling/heating chamber capable of cooling and heating foods. The cooling/heating chamber is divided into a heating zone that is a space where foods to be heated are placed, and a non-heating zone that is a space continuous with the heating zone where foods not to be heated are placed. The refrigerator further includes an oscillation electrode and a counter electrode that are arranged so as to face each other with the heating zone in between, and an oscillating unit that applies an AC voltage to between the oscillation electrode and the counter electrode.
