PROBLEM TO BE SOLVED: To provide a production method of a fluororesin composition containing a fluororesin and a crosslinked-rubber and giving molded products excellent in flexibility and fuel barrier property, to provide a fluororesin composition obtained by the method, and to provide molded products using the composition and excellent in flexibility and fuel barrier property. SOLUTION: The production method of a fluororesin composition comprises a step A for kinetically crosslinking at least one kind of fluororubber on a fluororesin melting condition to obtain a composition (a) containing a crosslinked-fluororubber at least partially crosslinked and the fluororesin and a step (B) for melting and kneading the composition (a) and fluoropolymer.
