There is provided a technique that includes arranging a plurality of substrates inside a process container in a vertical direction; and forming a film on each of the plurality of substrates by supplying a process gas into the process container. The act of forming the film includes: supplying the process gas into the process container; and performing pressure control such that a pressure inside the process container becomes a process pressure. A start timing of the act of supplying the process gas is adjusted with respect to a start timing of the act of performing the pressure control to adjust a thickness of a film formed on a substrate arranged on an upper portion of the plurality of substrates.
