To effectively achieve the photocatalyst effect or the like by titanium oxide, and the disease curing effect or the like by titanium carbide, to reduce the odor such as the personal odor or the like and to maintain the health by coating a base surface with titanium oxide particles and titanium carbide particles in the personal ornaments such as a key holder or the like.

A base 1 of name card size is formed by various kinds of materials such as paper, plastic, metal, composite material or the like, and one face (surface) of the base 1 is coated with titanium oxide particles 2a and titanium carbide particles 2b. The coating 2 is formed in such a manner that it is positioned at the body side when it is placed in, for example, a pocket. Thereby the ornaments are useful for the photocatalyst, antibacterial or pollutin control effects and the reduction of the smell and nicotine of cigarette, the odor such as the personal odor or the like by the titanium oxide particles 2a, and the metabolism, the muscle relaxation, the reinforcement, the recovery from fatigue, the maintain of health or the like by the titanium carbide particles 2b.
