PROBLEM TO BE SOLVED: To provide a composition for a sliding member imparted with a low coefficient of friction, abrasion resistance and scorching resistance and retaining such effects for a long time, and to provide a siding member using the same. SOLUTION: A polyamideimide resin for a sliding member comprises a polyamideimide resin obtained by copolymerizing a compound represented by formula 1 and/or formula 2, and a solid lubricant contained therein. In formula 1, R<SB>1</SB>and R<SB>2</SB>denotes a divalent alkyl group or an aryl group; X denotes a hydroxy, amino, carboxy, epoxy, thiol, methacryloyloxy or phenolic hydroxy group; and n denotes an integer of 1 or more. In formula 2, R<SB>3</SB>denotes a monovalent alkyl group or an aryl group;R<SB>4</SB>denotes an alkyl group or an aryl group which is between divalent and pentavalent; Y is bonded to a carbon in R<SB>4</SB>and denotes a functional group selected from a hydroxy, amino, carboxy, epoxy, thiol, methacryloyloxy and phenolic hydroxy group; n denotes an integer of 1 or more; and k denotes an integer of 1-4.
