Each of the tanks has an open end having the same shape as a profile shape of a corresponding one of regions of a surface of a workpiece, in which different types of films are to be formed, and stores a corresponding one of electrodeposition solutions used to form the different types of films in a state where the open end is in contact with the surface. The power supply device applies a predetermined voltage to between the workpiece that serves as a first electrode, and each one of second electrodes in the tanks.
