Abstract

A tool and device for analyzing a specific component in a sample liquid. An analyzing tool (Y) has a liquid-introducing opening (61) provided at the central part of the tool and plural flow passages (51) that are penetrated to the liquid-introducing opening (61) and allow the sample liquid introduced from the liquid-introducing opening (61) to flow from the central part toward a peripheral edge portion using a capillary phenomenon. Each of the flow passages (51) extends, for example, linearly from the central part to the peripheral edge portion, and the plural flow passages (51) are radially arranged.

Description

technical field [0001] The present invention relates to an analysis tool and an analysis device used for analyzing a sample liquid. Background technique [0002] As an analysis method of the sample liquid, for example, there is a method of optically analyzing the reaction liquid when the sample liquid and the reagent are reacted. When analyzing a sample liquid by this method, an analysis tool that provides a reaction field is used. An analysis tool has a plurality of flow paths so that a plurality of items can be analyzed using one sample liquid, or the same item can be analyzed with a plurality of sample liquids. [0003] For analytical instruments with multiple flow paths, such as Figure 13A as well as Figure 13B As shown, it is formed in a rectangular shape, and the main parts of the plurality of channels 90A, 90B are arranged parallel to each other. On the other hand, there is also an analytical tool in which a plurality of channels are arranged radially (for exampl...
