The present invention is a treatment agent for a moisture-permeable fabric having excellent moisture permeability, water resistance and launderability. The treatment agent comprises a fluorine-containing polymer having repeating units derived from: (a) a fluorine-containing monomer represented by the formula, CH2=C(-X)-C(=O)-Y-Z-Rf [wherein, X is a monovalent organic group excluding methyl groups, or a halogen atom, Y is -O- or -NH-, Z is a directly-bonded or divalent organic group, and Rf is a fluoroalkyl group with 1 to 6 carbons]; (b) a halogenated olefin monomer; and (c) a fluorine-free monomer that is used as necessary, does not have a fluorine atom, and has at least one carbon-carbon double bond. The dynamic viscoelasticity of the fluorine-containing polymer at 160°C is at least 100 Pa.s.
