Abstract
A sliding member having a supporting layer composed of an iron-based metallic material and a sliding layer formed on a surface of the supporting layer and composed of a copper-based metallic material. The surface of the supporting layer and the sliding layer have non-flat surfaces. A sliding surface having a non-flat surface is formed on the surface of the sliding layer. The sliding layer is formed on the roughened surface of the supporting layer by thermal spraying. The surface of the sliding layer is then subjected to a shot blasting treatment to form the sliding surface which has an uneven surface having an arithmetic average roughness (Ra) of more than 0 μm and 2.0 μm or less, a ten-point average roughness (Rz) of more than 0 μm and 7.5 μm or less and a surface hardness (Hv) of 150-250, and which slidably supports an object to be slid.
