Patent abstract
The present invention relates to an analytical tool including a plurality of flow paths 21 each including a detection cell 26 for detecting a particular component contained in a sample and configured to move the sample by capillarity, and a common path 22 connecting the plurality of flow paths 21 to each other. Each of the flow paths 21 includes a water stopper 29 for preventing the sample from flowing into the common path 22. Preferably, the water stopper 29 suppresses the movement of the sample by differentiating a cross sectional area at a target portion in a direction perpendicular to the sample flow direction from a cross sectional area at a portion near the target portion.
