<P>PROBLEM TO BE SOLVED: To stably supply a sample to enhance the reproducibility of sample analysis, in an analytical tool provided with a flow passage for moving the sample. <P>SOLUTION: This analytical tool X provided with a substrate 1, the first and second electrodes 11, 12 provided in the substrate 1, an insulation film 13 having opening parts 15a, 15b, and for covering the first and second electrodes 11, 12 under the condition where one portion in at least one out of the substrate 1 and the first and second electrodes 11, 12 is exposed via the opening parts 15a, 15b, and a reagent part 14 held in the opening parts 15a, 15b, has further one or more of additional opening part(s) 15c penetrated through the insulation film 13 provided adjacent to crossing directions N3, N4 crossing a sample moving direction N1 with respect to the opening parts 15a, 15b, in the insulation film 13. In the insulation film 13, water repellency is preferably higher than that of at least one out of the second electrodes 12 and the substrate 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
