[0049] Since the test tool 1B has the permeable layer 4B characterized by allowing the liquid to permeate in the thickness direction, as in the case of the first embodiment, it is possible to suppress the mutual interference of the adjacent chromophoric layers 3B, and it is also advantageous in cost. The miniaturization of the test tool 1B is actively pursued.

The present invention relates to technology concerning an analysis kit used to analyze specific components in a sample liquid. The present invention provides a test kit (1) including a penetration layer (4) and a plurality of coloration pads (3) in contact with the penetration layer (4), wherein a sample liquid (S) supplied to the penetration layer (4) is fed to each of the coloration pads (3) through the penetration layer (4). The penetration layer (4) allows liquid penetration mainly thicknesswise of the penetration layer (4) while restricting of liquid penetration in the planar direction of the penetration layer. <IMAGE>
Description
technical field [0001] The present invention relates to a test tool used when analyzing a specific component of a sample reagent and a manufacturing method thereof. Background technique [0002] like Figure 7 and Figure 8 As shown, there is a dry test tool in which a plurality of chromogenic layers 91 are arranged in a matrix on a carrier 90 . Each chromophoric layer 91 is covered by an extended permeable layer 92 . In such a dry test tool 9 , when a sample reagent is dropped on the stretched permeable layer 92 , the sample reagent permeates in the thickness direction while spreading in the plane direction of the stretched permeable layer 92 . As a result, the sample reagent is supplied to the entire chromogenic layer 91 . [0003] In the dry test tool 9, since the sample reagent is extended by extending the permeable layer 92 after the sample reagent is supplied, the sample reagent can be extended in the plane direction, therefore, liquid confluence occurs between adja...
