Abstract: The present invention aims to provide a highly heat-resistant sliding member for thrust bearing which can be manufactured at a low cost through formation of an intermediate layer by a conversion treating method for cost reduction, includes a chemical conversion coating formed on an iron-base member and a resin film containing a thermosetting resin and a solid lubricant which is formed on the chemical conversion coating, and can resist to high temperatures of 200° C. or higher. And the invention is concerned with the sliding member for thrust bearing, characterized by including an iron-base member performed shot blast treatment on which the chemical conversion coating of zinc calcium phosphate is formed and a resin film containing a thermosetting resin requiring baking at temperatures of 200° C. or higher and the solid lubricant is further formed.
