A method of forming a resist pattern including: forming a resist film on a substrate using a resist composition containing a base component (A) which exhibits decreased solubility in an organic solvent by action of an acid; exposing the resist film; and patterning by a negative-tone development using a developing solution containing the organic solvent, wherein the base component (A) contains a resin component (A1) having a structural unit (a0) which generates acid upon exposure and a structural unit (a1) derived from an acrylate ester which may have the hydrogen atom bonded to the carbon atom on the α-position substituted with a substituent and contains an acid decomposable group which exhibits increased polarity by the action of acid, and the developing solution contains a nitrile solvent. |
