PROBLEM TO BE SOLVED: To miniaturize a specimen at profitable manufacturing costs and at the same time to suppress the mutual interference between adjacent coloring layers in an analysis tool having a plurality of color development layers. SOLUTION: A testing tool 1 has the plurality of color development layers 3 and a permeation layer 4 collectively covering the plurality of color development layers and supplies a sample liquid supplied to the permeation layer 4 to respective color development layers 3 via the permeation layer 4. In the testing tool 1, the permeation layer 4 is composed so that a liquid is permeated mainly in the thickness direction or nearly the thickness direction of the permeation layer 4. In this case, the permeation layer 4 is composed of, for example, a permeation film where a plurality of pores 40 extended in the thickness or nearly in the thickness direction are formed. The permeation film is preferably formed by a track etching method and uses a honeycomb structure. COPYRIGHT: (C)2004,JPO
