1. A fluoride-based resin prepreg, consisting of:
a reinforced base layer; and
a fluoride-based resin layer covering the reinforced base layer;
wherein the fluoride-based resin layer includes 100 PHR of a fluoride-based resin and 20 to 110 PHR of an inorganic filler;
wherein based on a total weight of the fluoride-based resin, the fluoride-based resin consisting of 10 to 80 wt % of polytetrafluoroethylene (PTFE), 10 to 50 wt % of fluorinated ethylene propylene (FEP), and 0.1 to 40 wt % of perfluoroalkoxy alkane (PFA), and 0.1 to 5 wt % of ethylene-tetra-fluoro-ethylene (ETFE);
wherein a flowability of the fluoride-based resin prepreg is 4-16% and a pressing temperature of the fluoride-based resin prepreg is 308-375° C.
