Abstract
A half bearing includes: a semi-cylindrical bearing body having an inner circumferential surface that slides against a counterpart shaft; and a first groove formed in the inner circumferential surface so as to extend in a circumferential direction of the inner circumferential surface. In a cross section that is parallel with the circumferential direction and passes through the first groove, of the bearing body, an angle θ satisfies 90°≤θ≤105°, where the angle θ is formed by: a line connecting the inner circumferential surface side end of a mating surface located on a downstream side in a rotational direction of the counterpart shaft with the center point of a circular arc constituting an outer circumferential surface; and a line connecting an end of the first groove in the circumferential direction, on the upstream side in the rotational direction of the counterpart shaft, with the center point.
