Abstract
A sliding member having a hardness proper for an environment where a high-pressure is applied and having a good abrasion resistance. A sliding membercomprises a first sintered compact layerformed by solidifying an iron-based metallic powder with a sinter; and a second sintered compact layerformed by solidifying a copper-based metallic powder on a surface of the first sintered compact layerto improve a sliding characteristic. The second sintered compact layeris densified by a blast process where the powder is collided against a surface of the second sintered compact layer
