Abstract:
1. A biosensor comprising a development layer where an inspection target solution is developed, and holding at least a marker reagent part where a marker reagent is held so as to be dissolved by the development of the inspection target solution in a part of the development layer, and a reagent immobilization part where a reagent which specifically reacts to an analysis target in the inspection target solution is immobilized in a part that is chromatographically downstream relative to the marker reagent part of the development layer; the development layer is provided with a bleaching reagent area where a bleaching reagent having bleaching action is supported in a dry state where it can be dissolved, at least in a part of a sample application area where the inspection target solution is applied or downstream of the sample application area in the permeating direction of the inspection target solution; wherein, the bleaching reagent is sodium percarbonate.
