Abstract: The invention provides a cross-linked fluororesin having excellent abrasion resistance against metal. The cross-linked fluororesin is obtainable by cross-linking a fluororesin. The fluororesin contains a tetrafluoroethylene unit and a vinylidene fluoride unit, and the tetrafluoroethylene unit represents 50.0 mol % or more of all the monomer units constituting the fluororesin.
