To conduct the formation of a pattern with higher accuracy and high aesthetic property while maintaining the flushness of the surface of a metal body after the pattern is formed in a method of forming the pattern on the surface of the metal body.
A pattern forming method on the surface of the metal body includes the laminating step of laminating a plurality of metallic plates 11 of different materials, the connecting step of connecting a plurality of the laminated metallic plates 11 to one another to form multilayered metal body 14 in which a plurality of metallic layers 12 are laminated, the pattern forming step of forming a predetermined patternlike recess parts 16 on the surface of a multilayered metallic body 14, and the flattening step of making the surface height of the recess part 16 and the surface height of a non-pattern part 17 in the metallic body 14 uniform.
