Abstract
To provide a half bearing which has excellent abrasion resistance and surely forms an oil film under boundary lubrication in which it is difficult to form any oil film. A half bearingformed on a circular arc along a direction in which the member to be slid swings is provided with a porous layercomposed of Cu—Sn series alloy, which is formed on a surface of a metal substrate, and a sliding layerin which the porous layeris covered with resin materialincluding at least polytetrafluoroethylene and a carbon fiber. An uneven surfacehaving a height which maintains oil to form an oil film and maintains the oil so that the oil film is formed against abrasion when a member to be slid is sliding, is formed on a surface of the sliding layerslidably bearing the member to be slid.
