| description | Provided is a piston ring excellent in peeling resistance, wear resistance, and thermal conductivity. A piston ring 1 includes: an annular main body 2 having a pair of side faces 2a and 2b, an outer peripheral face 2d, and an inner peripheral face 2c; and a hard coating 11 provided on the outer peripheral face 2d. When a width of the main body 2 in a first direction D1 perpendicular to the pair of side faces 2a and 2b is set to h 1 mm, a width of the hard coating 11 in the first direction D1 is set to W mm, and a thickness of the hard coating 11 in a second direction D2 perpendicular to the outer peripheral face 2d is set to L mm, the following Formula (1) is satisfied. 0.003 ¤ L h 1 / W ¤ 0.151 |
