Disclosed is a powder that can be easily redispersed in a liquid medium such as water. The invention relates to a powder of the fluoropolymer, the fluoropolymer, -SO 2 Y, -COOR, -SO 3 X, -SO 2 NR 1 2 and -COOX (Y represents a halogen atom .R is .X represents an alkyl group having 1 to 4 carbon atoms, .M representing the M 1 / L or NR 1 4 represents a hydrogen atom or a metal whose valence is L, the L-valent metal is the periodic table From the group 1, group 2, group 4, group 8, group 11, group 12 or group 13. Each of R 1 independently represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. The dispersity calculated by filtering a composition having at least one group A selected from the group consisting of the above powder and water with a mesh having an opening of 20 μm is 50. % Powder characterized in that it is at least%.
