Abstract
A fluid handling device includes: a first channel through which liquid flows by capillarity; a liquid reservoir which communicates with an upstream end of the first channel and stores liquid; a liquid introduction part which communicates with the liquid reservoir and includes a taper part whose diameter decreases from an opening part toward the liquid reservoir; a stop valve disposed on a downstream end of the first channel and including a step part where a cross-sectional area of the channel in a direction orthogonal to a direction in which liquid flows discontinuously increases; and a second channel which communicates with a downstream end of the first channel, the second channel being a channel through which fluid flows.
