An excellent type of a film is realized by modifying conventional types of films. A carbonitride film of a predetermined thickness is formed on a substrate by performing, a predetermined number of times, a cycle including the steps of: supplying a source gas into a process vessel accommodating the substrate under a condition where a CVD reaction is caused, and forming a first layer including an element on the substrate; supplying a carbon-containing gas into the process vessel to form a layer including carbon on the first layer, and forming a second layer including the element and the carbon; supplying the source gas into the process vessel under a condition where a CVD reaction is caused to additionally form a layer including the element on the second layer, and forming a third layer including the element and the carbon; and supplying a nitrogen-containing gas into the process vessel to nitride the third layer, and forming a carbonitride layer serving as a fourth layer including the element, the carbon, and nitrogen.
