To provide a fluororesin film, of which discoloration, a change in the visible light transmittance and a decrease in the mechanical strength can be suppressed for a long period of time even though it contains titanium oxide, and a process for its production. A fluororesin film having a pigment dispersed in a fluororesin, wherein used as the pigment are composite particles each comprising a particle containing titanium oxide, a first covering layer containing cerium oxide and a second covering layer containing silicon oxide in this order from the inside, wherein the amount of cerium oxide is from 5 to 30 parts by mass based on 100 parts by mass of titanium oxide, the amount of silicon oxide is from 5 to 60 parts by mass based on 100 parts by mass of titanium oxide, and the average particle size of the composite particles is from 0.15 to 3 mum.
