1. A gene-detection device comprising:

  • an electrode having a single stranded nucleic acid probe immobilized on its surface which has a base sequence complementary to the gene to be detected;

    a reaction vessel in which a sample solution containing a gene sample which has been denatured into a single stranded form can react with said electrode to form a double stranded nucleic acid on the surface of the electrode;

    washing means to remove unreacted gene sample by washing the gene sensor after hybridization of the electrode with the gene sample; and

    a detection vessel to store a substance which binds specifically to the double stranded nucleic acid formed on the surface of the electrode and which is active physiochemically to the reaction system of said nucleic acid probe in said gene sample.
