Abstract
The present invention provides a fluidic device in which solutions of different concentrations can be easily obtained. The fluidic device includes: a first substrate and a second substrate which are stacked in a thickness direction; an undiluted solution introduction flow path which has an undiluted solution introduction port and which is constituted of a groove part provided on at least one of the first substrate and the second substrate; a first circulation flow path which is constituted of a groove part having an annular shape and having a shared part that shares part of a flow path with the undiluted solution introduction flow path and a non-shared part which is not shared with the undiluted solution introduction flow path and which is connected to a diluting solution introduction port; a second circulation flow path which is provided independently of the first circulation flow path and which is constituted of a groove part having an annular shape and having a shared part that shares some flow path with the undiluted solution introduction flow path and a non-shared part which is not shared with the undiluted solution introduction flow path and which is connected to a diluting solution introduction port; and/or a third circulation flow path which is constituted of a groove part having an annular shape and having a shared flow path that shares part of a flow path with the first circulation flow path and a non-shared flow path which is not shared with the first circulation flow path and which is connected to a diluting solution introduction port, wherein the undiluted solution introduction flow path includes a valve at both ends of the shared part.
