The present invention relates to an analysis tool including a reagent portion and electrodes. The electrodes include a porous conductive portion where the reagent portion is formed. The porous conductive section is formed by, for instance, coating at least a part of a surface and an inner surface of a porous body with a conductive film. The porous body is, for instance, an insulating fiber mesh cloth. Preferably, the electrodes are formed in a sheet shape.
