METHOD FOR MANUFACTURING PRODUCT WITH BRIGHT SURFACE

摘要

Provided is a method for manufacturing a product with a bright surface that has good surface brightness, has outstanding anti-corrosive and peeling-resistance properties, and can be manufactured in large quantities at low cost. The method is provided with the following: a step wherein a first metal film (23) is formed on a base coat layer (22) of a substrate (21) by electroless plating; a step wherein a second metal film (24) is formed on top of the first metal film (23) and the binding force between the films of a multi-layer metal film comprising the first and second metal films (23, 24) is made stronger by the binding force between the base coat layer (22) and the first metal film (23); a step wherein the entire multi-layer metal film is entirely divided into discontinuous sections by cracks (26) due to the internal stress difference between the substrate (21) and the multi-layer metal film to form an island-shaped metal film that comprises an aggregation of fine multi-layer metal regions (25) with an island-shaped structure and that has a unified bright surface; and a step wherein a translucent top coat layer (27) is formed so as to cover the fine multi-layer metal regions (25) and so as to come into contact with the base coat layer (22) by entering into the cracks (26).
