description Provided are: a fluororesin having excellent storage stability in the presence of a solvent and excellent adhesion to a base material; a method for producing the fluororesin; a composition capable of forming a coating film having excellent storage stability and excellent adhesion to a base material; and an article having excellent adhesion between a base material and the coating film. This fluororesin contains only a polymer having a fluorine-containing aliphatic ring structure in the main chain, the polymer containing at least one of an alkoxycarbonyl group having an alkoxy group having 1-3 carbon atoms and an amide group having a coupling group, and the IR spectrum of a 200 [mu] m thick cast film satisfies 0.010 < = B/A < = 0.7. A is the maximum value of the absorbance of 1, 780 to 1, 800 cm on the basis of a straight line connecting the absorbance of 1, 700 cm and the absorbance of 1, 925 cm . And B is the value of the absorbance at 1, 720 cm using a straight line connecting the abso
