    摘要： It is a microfluidic device including a flowchannel in which liquid flows. The flowchannel includes a main channel and a pair of branch channels provided across the main channel from each other to be each connected to the main channel. The main channel includes a first zone, a second zone, and a coupling zone that connects the first zone and the second zone. The second zone is smaller than the first zone in a distance between a bottom surface and a ceiling surface. The coupling zone is configured such that the distance between the bottom surface and the ceiling surface thereof gradually decreases towards the second zone from the first zone. A connection zone provided in the main channel and connected to each of the pair of branch channels overlaps with the coupling zone.

    摘要： A reaction method of performing an adsorption reaction in which a subject substance of analysis is specifically adsorbed in a first channel, the method includes: flowing a specimen liquid to a second channel connected to the first channel so that the specimen liquid is fed to the first channel, the specimen liquid containing the subject substance and a labeled substance that can be bonded to the subject substance; stopping feeding of the specimen liquid by detecting an event that a rear end of the specimen liquid flows into the first channel; joining a washing liquid to the rear end of the specimen liquid which stops in the first channel by flowing the washing liquid to a third channel that is converged to a connection portion of the second channel; and feeding the washing liquid to the first channel after the washing liquid is joined to the rear end.
