PROBLEM TO BE SOLVED: To provide a heat-treatment apparatus and a heat-treatment method with which each heat-treatment process in a furnace is performed under the atmosphere having suitable CP (Carbon Potential) with little variation, without mixing different kind of gas. SOLUTION: In the furnace 3 as the heat-treatment apparatus 1 for heat-treating a material 60 to be treated in the furnace 3 by supplying converted gas into the furnace 3 (carburizing furnace); every respective processes (each heat-treatment chamber 21, 22, 23, 24), the atmosphere in the furnace 3 is adjusted by supplying only converted gas generated in respectively prescribed carbon potential.
