| 1. A nucleic acid detection sensor comprising:
a plurality of nucleic acid chain fixed electrodes to each of which a probe nucleic acid chain is fixed;
a counter electrode which is arranged opposite to the nucleic acid chain fixed electrode, wherein a current flows between
the counter electrode and each nucleic acid chain fixed electrode; and
a reference electrode, wherein
the reference electrode and the nucleic acid chain fixed electrodes are formed on the same plane and the reference electrode
is formed so as to surround the nucleic acid chain fixed electrode.
