A microfluidic device for detecting a target gene according to the present invention comprises a plurality of capillary tubes which are partially immersed in a sample container containing sample solution and in which the sample solution flows by capillary phenomenon, and microbead packings arranged at one part in each capillary tube to be arranged on a flow path of the sample solution, wherein each of the microbead packings comprises: a packing tube arranged at the capillary tube so as to partially constitute the flow path of the sample solution, a plurality of microbeads contained in the packing tube and being in close contact with each other to form voids between the microbeads, and probe linkers formed on a surface of each microbead, wherein the probe linkers are configured to amplify a target gene in the sample solution by complementary bonding with the target gene, thereby detecting the target gene. |
