Disclosed is a fluorine-containing polymer compound containing first and second repeating units respectively represented by formulas (a-1) and (a-2), wherein R3 represents a fluorine atom or fluorine-containing alkyl group, each of W and W1 independently represents a bivalent linking group, R2 represents an acid-labile protecting group, each of R4, R5 and R6 independently represents a hydrogen atom, fluorine atom or monovalent organic group, and at least two of R4, R5, R6 and W or W1 may be combined to form a cyclic structure in formula (a-1) or (a-2). This polymer compound has a weight-average molecular weight of 1,000 to 1,000,000 and can provide a resist composition capable of forming a pattern with no swelling and no pattern falling down.
