A nucleic acid extractor reducing the possibility of cross contamination and a gene analysis apparatus having a nucleic acid amplification function and a detection function are provided. The nucleic acid extractor has a kit for nucleic acid extraction using silica-coated magnetic beads under the presence of a chaotropic agent, and includes a magnet cover 52 accommodating a magnet 44 in the inside and separating the magnet 44 and a reaction container 2, a wall part 53 covering the outside of the reaction container 2 in a state of accommodating at least a portion of the magnet cover 52 in the reaction container, and a wall part 53 covering a space above the reaction container 2 in a state of accommodating at least a portion of the magnet cover 52 in the reaction container. Scattering of liquid and aerosol can be prevented and the possibility of cross contamination can be reduced. |
