A photocurable resin composition containing a photopolymerization initiator and a (meth)acrylate monomer and/or oligomer, said (meth)acrylate monomer or oligomer having a cyclic structure, in which the atomic weight of carbon (Mcr) in said cyclic structure and the number of whole carbon atoms (MTOT) in said composition have the relation of Mcr/MTOT>0.1, or the total number (N) of carbon atoms in said cyclic structure, the total number of carbon atoms (Nc) in said composition and the total number of oxygen atoms (No) have the relation of N/(Nc-No)<4, and the composition has a kinetic viscosity of 10 mPa.s or below. This low-viscosity photocurable resin composition has excellent dry etching resistance and is applicable to optical nanoprinting.
