Problem to be solved: to examine the antibacterial property of a phosphor bronze thin film coated with coating agent, to reduce the discoloration caused by contact with the human body, and to provide an application that can utilize the antibacterial property of phosphor bronze.Solution: a phosphor bronze thin plate containing a composition of a coating phosphor bronze alloy containing 0 Sn ≦ 11 weight% tin and 0. Ltoreq. P.ltoreq.0.35% by weight of phosphorus, and the remainder is made of copper and excellent antibacterial property. The prevention of discoloration is two kinds of coating agents using air permeable, non waterborne coating agents, two types of coating agents, one is Paris len, and the other is coated phosphor bronze prepared with a specific composition such as silicone based coating agent.The coating phosphor bronze thin film plate having the above described antibacterial property can be prevented from spreading of infectious diseases by covering a portion directly touched by a handrail, a door knob or other hand such as a medical institution.No selection
