PROBLEM TO BE SOLVED: To provide a method for producing a protein or peptide in a cell-free protein synthesis using a cell-free extract in excellent protein synthesis efficiency. SOLUTION: This method for producing the protein or peptide comprises carrying out a RNA polymerase reaction using a cyclic ssDNA having a sequence complementary to the code sequence of the protein or peptide as a template to synthesize one or more mRNAs in which the complementary sequences of the cyclic ssDNA are transcribed on one mRNA, and synthesizing the protein or peptide in the cell-free protein synthesis system using the cell-free extract in the presence of the mRNA as a template.
