Abstract
A sliding member which has a hardness suitable for use under heavy-load conditions and which exhibits excellent abrasion resistance property. A sliding surface is formed on a surface of a sliding layer that slidably supports an object to be slid. The sliding surface is then shot-blasted and is formed to have an uneven shape exhibiting an arithmetic average roughness (Ra) of more than 0 to 2.0 μm, a ten-point average roughness (Rz) of more than 0 to 7.5 μm, and a surface hardness (Hv) of 150 to 250.
