A vapor phase deposition apparatus includes a chamber, a support table arranged in the chamber, and having a first support unit which is in contact with a back side surface of a substrate and on which the substrate is placed and a second support unit which is connected to the first support unit to support the first support unit, a heat source arranged at a position having a distance from a back side surface of the substrate, the distance being larger than a distance between back side surface of the support table and the heat source, and which heats the substrate, a first flow path configured to supply a gas to form a film into the chamber, and a second flow path configured to exhaust the gas from the chamber.
