    Abstract: A Ti film forming method includes a step (step (1)) of cleaning inside a chamber by introducing a cleaning gas containing fluorine into the chamber in a state where a wafer (W) is not on a susceptor; a step (step 2) of heating the susceptor in the state where the wafer (W) is not on the susceptor, jetting a processing gas containing Ti from a shower head into the chamber and forming a pre-coat film at least on the surface of the shower head; and a step (step (3)) of placing the wafer (W) on the susceptor (2) in a state where the susceptor is heated, supplying a processing gas into the chamber (1) and forming a Ti film on the wafer (W). The pre-coat film forming step is performed at a temperature lower than that in the film forming step.
