PROBLEM TO BE SOLVED: To provide an oil hole structure of a connecting rod bearing capable of preventing the occurrence of inconvenience such as seizure of the bearing caused by separation, by preventing the separation of a lining layer, by forming a cutting part and an exposure part in advance in a microscopic crack easily causing part. SOLUTION: This half-split-shaped connecting rod bearing 4 is formed by laminating the lining layer 42 on a back plate 41, by being interposed between a crankshaft and a connecting rod in an internal combustion engine. The cutting part 6 of continuously cutting the lining layer 42 in a tapered shape or a curved shape from a back plate 41 part in a longer range than the peripheral direction in the axial direction on which stress intensively acts, or the exposure part of exposing the back plate 41 part by eliminating the lining layer 42, is formed around an oil hole 5 formed in a proper place of the connecting rod bearing 4.
