A Ti-based 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 provided on a susceptor; a step (step 2) of heating the susceptor in a state where the wafer W is not provided on the susceptor, injecting a processing gas containing Ti from a shower head into the chamber, and forming a pre-coated film at least on the surface of the shower head; and a step (step 3) of mounting 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-based film on the wafer W. The pre-coated film forming step is performed at a temperature lower than that in the film forming step.
