A body member to be exterior parts of a portable device used both outdoors and indoors has a coating film containing a photochromic dye provided on at least a part of an internal surface of a transparent base material. Further, a plastic is used as the transparent base material. Besides, an ultraviolet absorbent that absorbs an ultraviolet ray having a wavelength shorter than a wavelength region in which a color developed by the photochromic dye is expressed is diffused in the transparent base material made of the plastic. In addition, the coating film containing the photochromic dye is formed by a coating liquid that contains a class of hindered amine light stabilizer or a class of hindered phenol light stabilizer.
