description	Provided is a piston ring having a thermal sprayed laminated coating tightly adhering thereto, which coating is excellent in wear resistance and scuffing resistance as well as less damaging to a mating material. The piston ring having a thermal sprayed base layer formed by thermal spraying of a mixed powder including at least Mo powder, Ni-based self-fluxing alloy powder and Cu and/or Cu alloy powder; and a thermal sprayed surface layer including Cu, which is formed on a sliding surface of the piston ring after forming the thermal sprayed. The thermal sprayed base layer at least includes 50 to 80 % by mass of Mo, 1 to 12 % by mass ofCu and/or Cu alloy, and a remainder: Ni-based self-fluxing alloy, the area ratio of Cu and/or Cu alloy phase which appears on the sliding surface of the thermal sprayed base layer is 0.5 to 15%, and the thermal sprayed surface layer includes 70 to 100% by mass of Cu.
