Abstract: Provided is a channel device that is capable of increasing the concentration of fine particles in a liquid only by use of fluid-dynamic flows without relying on electrostatic interactions. A channel device (1) in accordance with an embodiment of the present invention includes: a main channel (11) configured to allow a liquid containing fine particles to flow therethrough; a chamber (15) that is provided at an end of the main channel (11) and that is configured to store target fine particles which have increased in concentration; and a side channel (12) that is connected to a side face of the main channel (11) and that is configured to allow unwanted liquid to drain therethrough, wherein at least one of a height and a width of the side channel (12) is smaller than a particle size of the fine particles.
