<p>PROBLEM TO BE SOLVED: To obtain a surface structure of a musical instrument which enables a player to easily and cleanly hold the surface portion of a musical instrument base material to be touched by the mouth, etc., even if this portion is not carefully wiped and cleaned. SOLUTION: This surface structure has a surface skin material 3 which constitutes the surface of the musical instrument and a photocatalyst 5 which is disposed on the surface of the surface skin material 3 and is capable of receiving the light from outside. According to such constitution, the photodetectable photocatyalyst which is disposed on the surface of the musical instrument base material receives the UV rays by the sun or a fluorescent lamp, by which the dirt sticking to the surface of the musical instrument base material is decomposed. Also, the bacteria sticking thereto are exterminated by the OH and O2 generated by photodetection of the photocatalyst.</p> |
