Abstract
The present invention relates to an analytical tool () including a capillary () for moving a sample liquid introduced through a liquid introduction port (), and a window () for checking that the sample liquid of an amount necessary for measurement is supplied into the capillary (). In the analytical tool (), an opaque region () is defined between the liquid introduction port () and the window (). For example, the analytical tool () includes a substrate (), a cover () defining the capillary () together with the substrate (), and a working electrode () and a counter electrode () which include respective exposed portions () facing the interior of the capillary (). Preferably, at least part of the window () is formed at a region which avoids a position directly above the exposed portions ().
