PROBLEM TO BE SOLVED: To safely recycle a metal cabinet without generating harmful material by forming unevenness on the outer surface of a cabinet formed through a injection-molding metal material having a specific gravity lower than or equal to a specified value such as resin material and Mg alloy, and making the height difference at least a specified value. SOLUTION: When a closed-end vessel type rear cabinet 32 is isolated from a front plate 31, a cabinet 30 is constituted by injection-molding metal material which is Mg alloy having specific gravity lower than or equal to 2. An infrared- ray absorbing function coating film is formed on the inner surface side out of the surface of the cabinet 30. Also on the outer surface side of the cabinet 30, silicon-based coating material in which about 10 W% of photocatalyst particles of titanium dioxide and about 10 W% of photostorage material are mixed is sprayed, and for improving radiation efficiency, unevenness is formed. Height difference of the unevenness is made at least 0.7μm. As a result, the cabinet 30 can be safely recycled without generating harmful material.
