Abstract

A hydrogen vacuum furnace () is provided with a process chamber () wherein a subject () to be heated is stored; a heating chamber () wherein a heater lamp () is stored; and a crystal board () for separating the subject () and the heater lamp () one from the other. In the hydrogen vacuum furnace (), the subject () is heated by a radiant ray applied from the heater lamp (). The process chamber () and the heating chamber () are provided with gas feed ports () and exhaust ports (), respectively, for feeding and exhausting a gas. When the subject () is being heated, atmospheric pressure in each chamber is adjusted so that the heating chamber () is under positive pressure to the process chamber () by feeding or exhausting the gas.
