Abstract
A processing space is provided in a reaction container. One gas inlet port is provided at the lower end of the reaction container. A distribution plate is attached to the one gas inlet port. Another gas inlet port is provided at a lower side surface of the reaction container. Powder that is an object to be processed is stored on the distribution plate in the reaction container. The distribution plate is configured to let a gas pass and not let the powder pass. A nitrogen gas is introduced into the processing space through the distribution plate from the one gas inlet port, and a processing gas is introduced into the processing space from the other gas inlet port without passing through the distribution plate.
