The present invention addresses the problem of providing a sliding bearing with which it is possible to obtain a friction reducing effect and to suppress the total quantity of outflow oil. Provided is a manufacturing method for a sliding bearing (1) comprising vertically-arranged half members (2), (2) that are obtained by halving a cylinder in parallel with the axial direction and that have a metal layer (21) and a lining layer (22), which is provided to the inner peripheral surface of the metal layer (21). The manufacturing method has a thin groove forming step (S30) (first step) in which a thin groove (3) is provided circumferentially to the axial direction end of the lower half member (2) at the downstream side of the rotational direction. During the thin groove forming step (S30), the depth (d) of the thin groove (3) is formed so as to be shorter than the length obtained by subtracting, from the thickness (h1) of the lining layer (22), the sum of the tolerance (a1) of the thickness of the lining layer (22) and the tolerance (a2) of the depth of the thin groove (3). |
