Provision of a recombinant microorganism which has increased productivity of a protein or polypeptide of interest and a method for producing a protein or polypeptide of interest using the recombinant microorganism. The recombinant microorganism is produced by transferring a gene encoding a protein or polypeptide of interest to a microorganism strain, wherein the microorganism strain is prepared by: introducing a transcription initiation regulatory region that functions in the microorganism or both the transcription initiation regulatory region and a ribosome-binding site that functions in the microorganism into the upstream of a Bacillus subtilis prsA gene or a gene corresponding thereto in the genome of a parental microorganism, or introducing a gene fragment prepared by ligating a transcription initiation regulatory region that functions in the microorganism or both the transcription initiation regulatory region and a ribosome-binding site that functions in the microorganism to the upstream of the Bacillus subtilis prsA gene or a gene corresponding thereto into the genome of a parental microorganism; and deleting or inactivating one or more genes selected from an abrB gene, a dltA gene, a dltB gene, a dltC gene, a dltD gene, a dltE gene, and a gene (genes) corresponding thereto.
