ることを特徴とする複合筒部材の製造法。A slurry-like powder alloy material is produced by mixing wear-resistant metal powder with an organic solvent and an organic solvent-soluble resin, the powder alloy material is applied to a metal plate, and the powder alloy material and the metal plate are passed through a roller. After forming a laminate of uniform thickness by applying pressure, the laminate is sintered to sinter-bond the wear-resistant metal powder to the metal plate, and the sinter-bonded laminate is pressed. 1. A method for manufacturing a composite cylindrical member, characterized by forming the composite cylindrical member into a cylindrical shape whose inner side is made of the wear-resistant metal powder, and finishing the cylindrical laminate into a hollow cylindrical shape.
