  • Patent number: 7598090
    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.
