Abstract: Provided is a semi-cylindrical shaped half bearing. The half bearing has an inner surface forming a sliding surface and including a plurality of recesses. Each recess has a smooth recess surface and a peripheral edge. The recess surface forms a convex curve toward the outer diameter side of the half bearing in cross-sectional view in a direction parallel to a circumferential direction of the half bearing. The recess includes a groove forming zone adjacent to the peripheral edge of the recess. The groove forming zone includes a plurality of circumferential grooves. The circumferential grooves extend from the peripheral edge of the recess along the circumferential direction of the half bearing. The present invention also provides a cylindrical sliding bearing including the above half bearing.
