Abstract
A heating apparatus comprises a container having a work housing space formed therein, and a heat source for heating a work W in the work housing space . The apparatus further comprises a heat ray reflecting member having a heat reflecting surface thereof composed of a heat ray reflecting material, so as to allow the heat ray generated in the work housing space to reflect on the heat reflecting surface to thereby change the direction thereof towards the works W. The heat reflecting material is provided for reflecting heat ray in a specific wavelength band, comprises a stack of a plurality of element reflecting layers comprising materials having transparent properties to the heat ray, in which in the element reflecting layers, two adjacent layers are composed of a combination of materials differed from each other in refractive indices to the heat ray, while keeping difference between the refractive indices of 1.1 or larger.
