ABSTRACT:
A method of effecting high temperature vacuum heating and cooling suitable for conducting heat treatment to be performed on components used in a display apparatus. The heating/cooling method includes the steps of: heating a plate-like member placed in a reduced pressure atmosphere in a chamber by heating means opposed to the plate-like member; and cooling the plate-like member by a cooling plate which is opposed to the plate-like member, with the heating means therebetween, the cooling plate having a heat reflecting function. The cooling plate has an emissivity of not less than 0.50 but not more than 0.80 so as to minimize a sum of a requisite time for the heating step and a requisite time for the cooling step.
