Biosensor
First Claim
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.

Abstract
A biosensor is provided with an area in which a reagent having bleaching action is carried in a state where it can be dissolved, at least in a part of a sample application area to which an inspection target solution is applied or the downstream of the sample application area in the direction of the inspection target solution permeating, in a development layer. In the so-constituted biosensor, a colored component in the inspection target solution can be faded by the bleaching reagent, so that the color in parts other than a reactive area is reduced in consequence, whereby a visual judgment is possible and a more accurate measurement result in which a reading error by a measuring device is extremely suppressed can be obtained.
