The present invention provides a crosslinkable fluororesin composition with which it is possible to obtain a molded body, a crosslinked molded body, and a coated wire which have excellent heat resistance and are less likely to have a problem of staining. A crosslinkable fluororesin composition according to the present invention comprises: a fluororesin having a unit based on ethylene and a unit based on tetrafluoroethylene, is melt-moldable, and has a melting point of 210° C. or higher; a crosslinking agent having a plurality of unsaturated carbon bonds; and an antioxidant having at least one of a phenol group and a phosphorus atom and has a molecular weight 10 of 600 or more. A molded body, a crosslinked molded body, and a coated wire according to the present invention are obtained from the crosslinkable fluororesin composition according to the present invention.
