A fluoropolymer solid composition which contains a fine particle comprising a fluoropolymer, said fluoropolymer having an acid/acid salt group, said acid/acid salt group being a sulfonic acid group, -SO2NR<17>R<18>, a carboxyl group, -SO3NR<1>R<2>R<3>R<4>, -SO3M<1>1/L, -COONR<5>R<6>R<7>R<8> or -COOM<2>1/L (in which R<17> and R<18> are the same or different and each represents a hydrogen atom, an alkali metal, an alkyl group or a sulfonyl-containing group, R<1>, R<2>, R<3> and R<4> are the same or different and each represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, R<5>, R<6>, R<7> and R<8> are the same or different and each represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, M<1> and M<2> are the same or different and each represents a metal whose valence is L, and said metal whose valence is L is a metal belonging to the group 1, 2, 4, 8, 11, 12 or 13 of the periodic table); said fine particle comprising the fluoropolymer containing, at the proportion of at least 25% by mass thereof, a spherical fluoropolymer fine particle, and said spherical fluoropolymer fine particle being substantially spherical. |
