A nucleic acid substance is efficiently produced by cultivating a microorganism whose repressor protein for purine operon does not function in a normal manner, preferably a strain whose gene encoding the repressor protein on a chromosome (purR) is disrupted, in a culture medium so that the nucleic acid substance should accumulate in the culture medium, and collecting the substance from the culture medium.
