A positive resist composition including:
a polymeric compound (A1) having a structural unit (a0) that contains a “cyclic group containing —SO
2
—” on the side chain terminal, and a structural unit (a1) derived from an acrylate ester containing an acid dissociable, dissolution inhibiting group;
an acid generator component (B); and
a fluorine-containing resin component having a structural unit (f1) represented by general formula (f1-0):
wherein R represents a hydrogen atom, an alkyl group of 1 to 5 carbon atoms or a halogenated alkyl group of 1 to 5 carbon atoms; Q
0
represents a single bond or a divalent linking group having a fluorine atom; and R
X0
represents an acid dissociable, dissolution inhibiting group-containing group which may contain a fluorine atom, with the provision that at least one fluorine atom is contained in formula (f1-0).
