Patent ID: 7867298

Claim:
A reacting apparatus comprising: a high temperature reactor which causes a reaction of a reactant; a low temperature reactor which is provided in a position facing the high temperature reactor, and which causes a reaction of a reactant at a lower temperature than the high temperature reactor; a coupling section which couples the high temperature reactor and the low temperature reactor at respective opposing faces, which oppose each other, of the high temperature reactor and the low temperature reactor; a heat insulating package which accommodates the high temperature reactor, the low temperature reactor, and the coupling section, wherein an inner space of the heat insulating package is decompressed; and an infrared reflecting film to reflect infrared rays, wherein the infrared reflecting film is provided on (i) a portion of an inner wall surface of the heat insulating package facing the high temperature reactor, (ii) a portion of the inner wall surface of the heat insulating package facing the coupling section, and (iii) only a part closer to the high temperature reactor of a portion of the inner wall surface of the heat insulating package facing the low temperature reactor.
