The present invention has the object of providing a method of manufacturing a resist pattern in which an extremely fine and highly accurate resist pattern can be formed which is obtained using the resist composition for forming a first resist pattern in a multi-patterning method such as a double patterning method. The resist processing method comprising; forming a first resist film by applying a first resist composition onto a substrate and drying, the first resist composition comprising a resin (A), a photo acid generator (B) and a cross-linking agent (C), the resin (A) having an acid-labile group, being insoluble or poorly soluble in alkali aqueous solution but of being rendered soluble in alkali aqueous solution through the action of an acid; prebaking; exposure processing; post-exposure baking; developing; hard-baking the first resist pattern; and obtaining a second resist film; pre-baking; exposure processing; post-exposure baking; developing to obtain a second resist pattern.
