A probe unit for identifying a target nucleotide region in a target nucleic acid, the unit being provided with an electrode, a probe bound to the electrode and recognizes the target nucleic acid, and a hole-transfer-inducing agent bound to the probe, wherein a nucleotide region corresponding to the target nucleotide region is located between the hole-transfer-inducing-agent-binding site and the electrode-binding end of the probe. A state of the target nucleotide region in the target nucleic acid can be identified by comparing electrochemical signal levels by energy-induced hole transfers before and after the hybridization of such a probe unit with the target nucleic acid.
