(57) [Summary] [Problems] An object of the present invention is to simplify the operation, to reduce the size of the entire apparatus, to expand the versatility, and to further improve the target in the test sample. Provided are a gene detection method and a detection chip capable of detecting a target gene even when the concentration of the gene is low. SOLUTION: The detection method comprises a test sample and a solution for gene synthesis reaction, wherein the mixed solution before performing the gene synthesis reaction can specifically bind to the gene, and Response in the presence of a highly active gene-binding substance and the product solution obtained by performing a gene synthesis reaction on a mixture containing a test sample and a solution for gene synthesis, With the electrochemical response in the presence of an ionic substance. The detection chip includes a gene synthesis reaction site 1, a measurement site 2 for electrochemical response provided with electrodes 7 and 8, and a flow capable of sending a liquid in the gene synthesis reaction site from the gene synthesis reaction site to the measurement site. Road 4 is included. |
