PROBLEM TO BE SOLVED: To provide a coating member in which blow holes developed during depositing a coating by thermal spraying are reduced and consequently the strength of the deposited coating is enhanced. SOLUTION: The coating member is composed of a base material 1 made of Al, and of a coating 2 made of Cu, on the surface of the base material 1, deposited by the thermal spraying. The coating 2 is made fine by collision of solid against the surface of the coating 2. The blow holes developed by the deposition of the coating by the thermal spraying are reduced with the fining treatment, and the strength of the coating can be improved.
