A chromatography immunoassay device is described which can be used more easily, is protected from moisture and/or oxygen more effectively and can be produced at a lower cost than known chromatography immunoassay devices. The chromatography immunoassay device of the present invention is one in which one or more chromatography strips are stuck on a substrate made of a plate, each of the chromatography strips is sealed by closely adhering a substrate portion surrounding each chromatography strip to a seal film located on the chromatography strip, and the seal film and/or substrate possesses a film containing a dehumidifying agent and/or a film containing an oxygen absorbing agent.

Cette invention concerne un dispositif d'analyse immuno-chromatographique, lequel est d'une utilisation simple, possède une meilleure protection contre l'humidité et/ou l'oxygène, et peut être fabriqué à faible coût par rapport aux dispositifs d'analyse immuno-chromatographique connus. Ce dispositif d'analyse immuno-chromatographique appartient au type de ceux dans lesquels on dispose une ou plusieurs bandes de chromatographie sur un substrat consistant en une plaque. Chaque bande de chromatographie est scellée en faisant adhérer fermement une partie du substrat qui l'entoure à un film d'étanchéité situé sur la dite bande. Le film d'étanchéité et/ou le substrat comprennent un film contenant un agent de déshumidification et/ou un film contenant un agent absorbant l'oxygène.
