<P>PROBLEM TO BE SOLVED: To supply lubricating oil to an overall bearing sliding face including a bearing sliding face in the vicinity of a central part in the circumferential direction in a semi-cylindrical bearing with a lubrication groove, in the sliding bearing for an internal combustion engine supporting a crankshaft. Ž<P>SOLUTION: When the position of the central part in the circumferential length of the semi-cylindrical bearing 10 is set at an angle of 0° in the circumferential direction, the lubrication groove 16 is formed at least in a range from a position at an angle of -45° in the circumferential direction to a position at an angle of +45° in the circumferential direction on the bearing inner peripheral face. A groove bottom face of the lubrication groove 16 is formed to be an irregular face comprising a plurality of mountains 16A and a plurality of valleys 16B continuously undulating without a flat part at least in the range from the position at an angle of -45° in the circumferential direction to the position at an angle of +45° in the circumferential direction on the bearing inner peripheral face.
