The invention concerns a decorative casing fabricated by bonding a film having a polarizing characteristic to the surface of the casing body via an adhesive layer, and an object of the invention is to provide the casing with enhanced decorativeness by designing the adhesive layer so as to render various color effects in addition to the effect rendered by the polarizing characteristic. The polarizing film is bonded to the surface of the casing body via the adhesive layer containing a special-effect material having a color effect. According to the present invention, by directly bonding the polarizing film to the casing via the adhesive layer that produces a desired color effect, other effects such as color hue can be conferred in the film bonding step, and thus a casing having an excellent decorative effect can be manufactured by a simple process without increasing the number of process steps.

A decorative casing as claimed in claim 1, wherein the surface of said casing body is formed with projections and depressions. 22. A decorative casing as claimed in claim 1, wherein said adhesive layer comprises at least two kinds of special-effect materials. 23. A decorative casing as claimed in claim 1, wherein the surface of said casing body to which said film is bonded is flat, and a casing surface opposite from said surface of said casing body contains projections and depressions. 24. A decorative casing as claimed in claim 1, wherein said casing body is formed from a resin. 25. A decorative casing as claimed in claim 1, wherein said casing body is formed from metal. 26. A decorative casing as claimed in claim 23, wherein said metal includes at least one substance selected from the group consisting of stainless steel, aluminum, titanium, silver, magnesium, and an alloy thereof. 27. A decorative casing as claimed in claim 1, wherein said casing body is formed from glass. 28. A decorative casing as claimed in claim 1, wherein said casing body is formed from a structure made of carbon. 29. A decorative casing as claimed in claim 1, wherein said film is formed by laminating together a plurality of films having different refractive indexes. 30. A decorative casing as claimed in claim 1, wherein said special-effect material forms a decorative pattern, a letter, symbol or both on the surface of said casing body. 31. A decorative casing as claimed in claim 1, wherein a colorless, colored transparent or semi-transparent cover layer is formed on a surface of said film.
