Provided is a labeling method for nucleic acid including a reaction step for hybridizing a nucleic acid probe that has a nucleotide sequence complementary to that of a nucleic acid to be labeled and contains a reactive nucleobase derivative incorporated at a position complementary to that of a target nucleobase as a target of labeling in the nucleic acid to be labeled, to the nucleic acid to be labeled; a transferring step for transferring a transfer group contained in the reactive nucleobase derivative to the nucleotide residue containing the target nucleobase in the nucleic acid to be labeled; and a labeling step for labeling the transfer group transferred to the nucleotide residue with a radioactive material.
