Abstract
A sliding member includes convex portions are formed by directly quenching a sliding surface of a sliding member in a line shape or a dot shape, and concave portions are formed in indirectly quenched portions adjacent to the directly quenched portions. An irregular surface is formed on the sliding surface by the directly quenched portions and the indirectly quenched portions. The directly quenched portions are formed in a lattice shape, a parallel straight line shape, a concentric circle shape or a spiral shape. With the irregular surface on the sliding surface by the directly quenched portions and the indirectly quenched portions, the seizure resistance can be improved.
