Abstract

PURPOSE:To increase emitted energy covering a wide range while enabling all food-stuff to be efficiently heated by forming a supporting plate of a crystallized glass for transmitting a near infrared ray region while emitting light in a far infrared ray region. CONSTITUTION:A supporting plate is composed of a crystallized glass such as, for instance, beta sponging system crystal glass for transmitting light in a near infrared ray region while radiating light in a far infrared ray region. That is, when the infrared rays heading for the supporting plate 8 from an infrared ray lamp 10 permeates the supporting plate 8, a larger amount of the near infrared rays than before can be emitted to a cooking utensil 20 because this supporting plate 8 is excellent in transmissivity of light in the infrared ray region. And this supporting plate 8 is heated by residual heat and surrounding heat for radiating light in the far infrared ray region by itself to emit the far infrared rays. Thereby, emission energy is increased covering a wide range from the near infrared ray region to the far infrared ray region thus being able to efficiently heat food-stuff in a wide range from the food-stuff desirably heated with infrared rays to the food-stuff desirably heated with far infrared rays.
