The present invention relates to a fluorine-containing resin composition, and a resin vanish, a fluorine-containing dielectric sheet, a laminate, a copper clad laminate and a printed circuit board containing the same. The fluorine-containing resin composition comprises 30 wt. %-70 wt. % of a fluorine-containing polymer, 30 wt. %-70 wt. % of an inorganic filler which includes the following particle size distribution: D10 is greater than 1.5 μm; and D50 is 10-15 μm. In the present invention, the selection of an inorganic filler with a specific particle size distribution can ensure that the boards prepared by the fluorine-containing resin composition have excellent dielectric properties and voltage resistance performance, even if the inorganic filler is added in a large amount.
