Nucleic acid analysis device and nucleic acid analyzer using the same

A nucleic acid analysis device for analysis of nucleic acid in a sample through fluorometry, comprising:

• a flat supporting substrate;
• a metallic body, an insulating layer, and a metallic body that are stacked in listed order on the supporting substrate in a direction perpendicular to a surface of the supporting substrate;
• and
• a nucleic acid probe provided in the insulating layer for the analysis of the nucleic acid in the sample.

A nucleic acid analysis device for analysis of nucleic acid in a sample through fluorometry, comprising:

• a flat supporting substrate;
• a metal structure of a shape having a vertex and a thin film layer made of a material other than the metal of the metal structure, the metal structure and the thin film layer being provided on the supporting substrate in a manner that a part of the metal structure is exposed from the thin film layer;
• and
• a nucleic acid probe for the analysis of the nucleic acid in the sample, the nucleic acid probe being provided on the exposed surface of the metal structure.
