Abstract
An object of the present invention is to provide a fluidic device in which a solution can be introduced into a flow path and be quantified while preventing air bubbles from being generated. A pair of substrates are provided which are stacked in a thickness direction and in which one substrate includes a flow path constituted by being covered by another substrate. The flow path includes a quantification part that is able to quantify a solution to a predetermined amount. The quantification part includes: a pair of merging/branching portions each of which is surrounded by a contour that matches each of line segments connecting apex positions of an equilateral triangle in a view of the thickness direction or a contour parallel to each of the line segments and at which merging or branching of the solution is performed; and a connection portion that connects the pair of merging/branching portions via one of the apex positions of the equilateral triangle of the merging/branching portion. A valve which regulates a fluid flow in the flow path is provided at the apex position in the merging/branching portion at which the connection portion is not arranged.
