Disclosed is a connecting rod bearing for a crankshaft of an internal combustion engine, the connecting rod bearing comprising a pair of semi-cylindrical bearings. In at least one of the semi-cylindrical bearings, a front side circumferential groove is formed from the front side circumferential end surface, and in the opposed semi-cylindrical bearing, a rear side circumferential groove is formed from the rear side circumferential end surface. A circumferential length of the front side circumferential groove is larger than a circumferential length of the front side crush relief, and a circumferential length of the rear side circumferential groove is smaller than a circumferential length of the rear side crush relief.
