Nucleic acid analysis device

A nucleic acid analysis device comprising:

• a flow cell for use in analysis of nucleic acid having a substrate for use in analysis of nucleic acid,
• the substrate for use in analysis of nucleic acid having a plurality of analysis areas partitioned on the substrate to perform measurement by sequentially changing each analysis area,
• the analysis area has an absorbent portion capable of absorbing a DNA fragment or a vector where the DNA fragment is borne and a non-absorbent portion other than the absorbent portion,
• at least a part of the non-absorbent portion being provided with a marker portion having a predetermined shape to compute a position of the analysis area;
• a circulation unit that circulates a fluid in a flow passage of the flow cell for use in analysis of nucleic acid;
• a temperature control unit that controls a reactive temperature of the DNA fragment;
• an irradiation unit that irradiates excitation light onto an analysis area serving as an analysis target through the light-transmitting cover;
• a detection unit that detects fluorescence emitted from the DNA fragment by irradiating the excitation light using the light-transmitting cover and detects a position of the marker portion in the analysis area from the detected fluorescence;
• and
• a carriage unit that carries the flow cell for use in analysis of nucleic acid and shifts the analysis area to a predetermined position by delivering the flow cell for use in analysis of nucleic acid with respect to the marker portion.
