PROBLEM TO BE SOLVED: To provide a wear-resistant chain capable of restricting outbreaks of peeling under the environment wherein the chain is used, and improved in wear resistance exhibiting high sliding performance for a long time. SOLUTION: In this chain, both ends of a bush are fixed by respectively fitting them in bush holes of a pair of inner plates, and both ends of a connecting pin loosely passing through the bush are fixed by respectively fitting them in pin holes of a pair of outer plates arranged both outside of the pair of inner plates. At least one of a surface of the connecting pin and an inner surface of the bush has irregularity on a base material thereof and has a DLC film for covering the irregularity to solve the described problems.
