FLUID HANDLING DEVICE, FLUID HANDLING METHOD, AND FLUID HANDLING SYSTEM

摘要

A fluid handling device (100) comprises: a first channel (130); an air pool part (170); an air discharge port (180); a second channel (140); and a connection part (150). The first channel (130) is a channel through which a fluid can move by capillary action. The air pool part (170) is connected to one end portion of the first channel (130), and is formed such that a through hole that communicates the air pool part (170) with the outside can be formed. The air discharge port (180) communicates with the outside. The second channel (140) communicates with the air discharge port (180). The connection part (150) connects the first channel (130) and the second channel (140) with each other, and has a cross-sectional area smaller than the cross-sectional area of the second channel (140).
