    Abstract: A film forming apparatus for forming a film on a substrate in a vacuum container includes a rotary table, a first processing gas supply unit for supplying a first processing gas, a gas nozzle for supplying a second processing gas, a nozzle cover installed to cover the gas nozzle, and a separation gas supply unit. The nozzle cover includes a ceiling wall, and an upstream side wall and a downstream side wall extended downward from each edge of upstream and downstream sides of the ceiling wall in the rotating direction of the rotary table. The inner surface of the gas nozzle in the upstream side wall is an inclined surface, and an angle (θ1) between the inner surface of the gas nozzle in the upstream side wall and a surface of the rotary table is smaller than an angle (θ2) between the inner surface of the gas nozzle in the downstream side wall and the inner surface of the gas nozzle.
