A film growing method includes: (A) attaching wall members to ends of a film grown surface of a base material; (B) growing a film on the film grown surface by a cold spray method; and (C) removing the wall members after a thickness of the grown film on the film grown surface becomes equal to a desired film thickness. It can be prevented that the side ends of the grown film are formed in a slope when a thick film is to be grown by using the cold spray. |
