Abstract
A formation method of a coating that coats a coated body with the coating includes: generating cylindrical plasma in a vacuum deposition chamber as well as supplying material gas into the vacuum deposition chamber; applying pulse voltage to the coated body; and attaching a shield member that shields an uncoated member to an uncoated part where the coating of the coated body is not formed with separation spacing over a coated part where the coating is to be formed for preventing decrease of hardness of the coating in the coated part.
