PROBLEM TO BE SOLVED: To prevent the surface of a case body component from being contaminated or flawed, make elegant the outer appearance of the case body component and moreover make it possible to exchange easily a protective sheet even if a bonding agent is not applied on the protective sheet. SOLUTION: A case body component is formed into a prescribed shape using a steel plate with a surface protective sheet 2, which is formed by making the plastic protective sheet 2 coat on the surface of a steel plate 1 for structure using a pressure sensitive adhesive double-coated tape 3, or the sheet 2 is applied on the surface of the case body component formed into the prescribed shape of the steel plate 1 with the adhesive tape 3, and as the bonding agent which is used to a bonding agent layer of the adhesive tape 3, a bonding agent, which holds a stable adhesive force in a natural state and has an adhesive force capable of separating easily the sheet 2 from the plate 1 when the sheet 2 is separated from the plate 1, is used. |
