A microwave oven is provided according to which food is cooked while a temperature sensor is inserted in the food and the heating of the food is interrupted in response to an output signal of the temperature sensor. The temperature sensor comprises a hollow skewer, a bellows which is attached to the skewer and in which is sealed a liquid of high coefficient of thermal expansion, and a sound generating body of a plate spring for generating a sound when the hollow skewer is heated by the food, the liquid is expanded, the bellows is stretched, and the force generated thereby overcomes the biasing force. The microwave oven stops heating and cooking when a sound is generated. |
