A test paper having high measurement accuracy and excellent reaction efficiency between a specimen and a reagent component is provided. A porous membrane having a first surface and a second surface, a first reagent region having a first reagent component having a first enzyme, and a second reagent having a second enzyme. A test paper having a second reagent region having a component, wherein the first and second reagent regions are differently distributed in the thickness direction of the porous membrane. This problem is solved by the test paper formed inside. [Selection] Figure 1
