Claim:
1. A method for producing a nanoimprint mold in which a first pattern and a second pattern which is larger in size than the first pattern are formed on the same surface, the method comprising: preparing a base material on which a first hard mask layer and a second hard mask layer are laminated in the order of description, and forming a first resist pattern on the second hard mask layer positioned on an upper layer of a first pattern region where the first pattern is to be formed in the base material; forming a sidewall pattern on a side wall of the first resist pattern; etching the second hard mask layer by using the sidewall pattern as a mask, and forming a second hard mask pattern; after etching the second hard mask layer, forming a second resist pattern on the first hard mask layer positioned on an upper layer of a second pattern region where the second pattern is to be formed in the base material; etching the first hard mask layer by using the second hard mask pattern and the second resist pattern as a mask, and forming a first hard mask pattern; and etching the base material by using the first hard mask pattern as a mask, and forming the first pattern and the second pattern.
