PROBLEM TO BE SOLVED: To provide a fluorine resin substrate exhibiting suppression of an elevation of dielectric tangent to the elevation of a frequency band. SOLUTION: This fluorine resin substrate is characterized by using a prepreg 4 as an insulation material 2 to make≤10 elevation ratio of dielectric tangent at 75 GHz to that at 1 GHz by impregnating 60-95 wt.% fluorine resin to an aramide fiber sheet material.
