Abstract
The present invention aims at providing a fluidic device that can hold a large amount of solutions in a reservoir without depending on an attitude. The reservoir includes a meandering flow path including: a plurality of first flow paths that extend linearly along a first direction and that are arranged to be spaced in a second direction crossing the first direction; and a second flow path that extends linearly along the second direction such that a connection between first end sides of the adjacent first flow paths and a connection between second end sides of the adjacent first flow paths are alternately switched along the second direction for each first flow path, wherein the meandering flow path meanders along the second direction. When the length of each of the first flow path and the second flow path is L, a surface tension is γ, the density of the solution is ρ, the acceleration which includes a gravity and which is applied to the solution is G, the wetted perimeter length of the first flow path and the second flow path is Wp, a cross-sectional area of the first flow path and the second flow path is A, a receding contact angle is α, and an advancing contact angle is β, a relat…
