Abstract
The present invention relates to an analyzing instrument (1A) which includes a capillary (31), a fluid feed port (20) for introducing a sample liquid to the capillary (31), and a fluid feed promoter (6) for promoting the introduction of the sample liquid into the feed port (20). The capillary (31) of the analyzer (1A) may be formed on a substrate (2) for example. The fluid feed promoter (6) may include at lease one of a water-absorbing layer having a higher water-absorbing capacity than the substrate (2) and an adhesive layer having a greater adhesion to the skin than the substrate (2).
