Abstract
The present invention provides a heating apparatus that displays a high heating efficiency and a long product life. In addition, present invention provides a heating apparatus that has no limitations with respect to the materials comprising its heat insulating material, which displays an even greater product life and, moreover, can be manufactured easily at low cost. This heating apparatus is characterized in comprising: a loading plate on which an object to be heated is placed; a support plate that is integrated into a single body with the loading plate; a heating element that is sandwiched in between the loading plate and the support plate; and at least one pair of electrodes, one terminal of which is connected to the aforementioned heating element; wherein, the aforementioned loading plate and support plate each respectively comprises a ceramics sintered body, such that the coefficient of thermal conductivity of the ceramics sintered body comprising the loading plate is greater than the coefficient of thermal conductivity of the ceramics sintered body comprising the support plate. In addition, a heat insulating material may be installed at the base of at least the aforementioned heating element.
