PROBLEM TO BE SOLVED: To provide a sliding member capable of suppressing friction force during sliding, and a method for producing the sliding member in a simple manner.SOLUTION: There is provided a sliding member comprising: a polytetrafluoroethylene porous body that includes a polytetrafluoroethylene resin and a scale-like material having a laminated structure, and has a porosity of 20 to 50%; and a liquid lubricant with which the polytetrafluoroethylene porous body is impregnated. A method for producing a sliding member includes the steps of: mixing a polytetrafluoroethylene resin, a scale-like material, and a pore-forming agent to obtain a mixture; molding the mixture to obtain a molded article; removing a pore-forming agent from the molded article to obtain a polytetrafluoroethylene porous body; and impregnating the polytetrafluoroethylene porous body with a liquid lubricant.SELECTED DRAWING: None |
