To provide a coating film forming apparatus capable of completely removing excess coating treatment liquid.

In the coating film forming apparatus 100, a coating film control part 101 having a member holding basket holding a member is horizontally rotated in an arrow mark a11 direction and an arrow mark a13 direction, and is vertically rotated in an arrow mark a15 direction and an arrow mark a17 direction. As a result, the member, to which the coating treatment liquid is stuck, is rotated in the horizontal direction and the vertical direction to uniformly remove a useless coating treatment liquid in the coating treatment liquid stuck on the member, thereby forming a uniform coating film on the member.
