Abstract: A sliding member formed of a resinous material is in sliding contact with a steel member in an automotive internal combustion engine. The resinous material includes a thermoplastic resin composition which includes a fluororesin in an amount ranging from 5 to 40 parts by weight, and a thermoplastic resin other than the fluororesin, in an amount ranging from 95 to 60 parts by weight. The fluororesin contains crosslink formed between at least a part of carbon atoms forming part of a molecule chain of the fluororesin and at least a part of carbon atoms forming part another molecular chain of the fluororesin, and active end group formed at least a part of the molecule chain of the fluororesin.
