The present invention can be produced and produced at low cost, the generation of stagnant flow of a liquid sample can be suppressed, the microbeads can be injected, filled and transported smoothly and conveniently, and a new technology can also suppress dust generation. Means and a novel nucleic acid extraction method using the same are provided. It is a microchip in which the micro flow path 3 is formed by the groove part 11 and 21 provided in the joining surface of the upper and lower boards 1 and 2, The micro flow path 3 is the center part of the upper and lower sides, the left and right sides of the cross section, The clearance gap 31 with the flow path cross section reduced is provided in the microbeads. |
