The copper alloy includes: less than 0.5% by mass of Ni; 0.2% by mass or more and 0.9% by mass or less of Bi; 12.0% by mass or more and 20.0% by mass or less of Zn; 1.5% by mass or more and 4.5% by mass or less of Sn; and 0.005% by mass or more and 0.1% by mass or less of P; wherein the total content of Zn and Sn is 21.5% by mass or less, and the balance is a trace element(s) and Cu.
