Deterioration of the degree of vacuum in a vacuum chamber is prevented while securing adequate cooling performance by gas cooling. A substrateis provided in a vacuum, and the cooling bodyis provided close to a film non-formation surface of the substrate. A thin film is formed by depositing a film forming material on a film formation surface of the substratewhile introducing a cooling gas into between the substrateand the cooling body. At this time, a gas which reacts with the film forming material is introduced as the cooling gas.
