摘要： A coating material composition containing a fluororesin, a polymer (I) containing a polymerization unit (I) derived from a monomer represented by the general formula (I) below, and an aqueous medium, wherein the content of the polymer (I) is 2,000 ppm by mass or less based on the coating material composition:


CX1X3═CX2R(—CZ1Z2-A0)m  (I)

wherein X1 and X3 are each independently F, Cl, H, or CF3; X2 is H, F, an alkyl group, or a fluorine-containing alkyl group; A0 is an anionic group; R is a linking group; Z1 and Z2 are each independently H, F, an alkyl group, or a fluorine-containing alkyl group; and m is an integer of 1 or more.
