A connecting rod bearing for an internal combustion engine is provided to promote the exhaustion of the foreign material existing in a columnar groove. A connecting rod bearing for an internal combustion engine comprises a pair of semicircular bearings(24,26). The semicircular bearing comprises a columnar edge(24A,24B,26A,26B) and has a circumferential groove(24C) on an inner surface within the maximum angle at the circumference range of figure 45 measured toward the circumference center domain of the semicircular bearing from a first columnar edge facing to the same direction with the rotating direction of a crank axle(12). The axle groove is connected to the columnar groove as a flow path of the lubricating oil by forming an axial groove(24E) in order to be extended through the total length overall between amount axial ends of the semicircular bearing along a facing end unit.
