<p>According to a fluorine resin substrate of the present invention, a dielectric layer whose main component is fluorine resin is formed on a metal conductor, the generation of warp during reflow is sufficiently suppressed, and sufficiently excellent high frequency characteristics can be achieved. Provided is a fluorine resin substrate whose dielectric layer contains hollow glass beads, a fluorine resin substrate in which the metal conductor has a surface roughness (Rz) of 2.0 mum or less, a fluorine resin substrate in which fluorine resin is irradiated with ionizing radiation with an irradiation dose of between 0.01 kGy and 500 kGy, and a fluorine resin substrate in which fluorine resin is one or more of polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA), tetrafluoroethylene-hexafluoropropylene copolymer (FEP), and tetrafluoroethylene-ethylene copolymer (ETFE).</p> |
