PROBLEM TO BE SOLVED: To provide a nucleic acid detection device which reduces an in-plane temperature distribution in a DNA chip, and a nucleic acid detection apparatus.SOLUTION: A nucleic acid detection device comprises a first component, and a second component. The first component comprises: a substrate; a plurality of sensors which are disposed on the surface of the substrate to detect a nucleic acid; a first electrode pad which is disposed on the surface of the substrate to take out a detection signal detected by the sensors; and a second electrode pad which is disposed at a different position from the first electrode pad on the surface of the substrate to take out the detection signal detected by the sensor. The second component comprises a groove part which is formed on the surface facing the surface of the substrate to face the sensors and to be a passage for feeding a reagent onto the sensors. The first electrode pad and the second electrode pad are arranged to sandwich a passage region defined by the groove part on the surface of the substrate. |
