The present invention is provided with: a microneedle provided with a facing surface facing a puncture object to be pierced by the microneedle, and an adherend surface which is a surface on the reverse side from the facing surface, the microneedle having one or more protruding parts on the facing surface a recessed container for accommodating the microneedle a plate-shaped lid part connected to the recessed container so as to cover an open part of the recessed container, the lid part spreading from the adherend surface to the periphery of the adherend surface and an adhesive part for bonding the lid part and the adherend surface. The recessed container is configured so that the connection thereof to the lid part is released when the recessed container receives a force directed away from the lid part in a state in which the microneedle is bonded to the lid part by the adhesive part. The adhesive part has a first contacting surface for making contact with the lid part, and a second contacting surface for making contact with the adherend surface and spreading from the adherend surface to the periphery of the adherend surface, and making contact with a portion of the puncture object positioned in the periphery of the facing surface when the puncture object is pierced by the protruding parts.La présente invention concerne : une micro-aiguille pourvue dune surface de face faisant face à un objet de ponction à percer par la micro aiguille, et une surface adhérente qui est une surface sur le côté opposé de la surface de face, la micro-aiguille ayant une ou plusieurs parties saillantes sur la surface de face un conteneur évidé pour recevoir la micro-aiguille une partie de couvercle en forme de plaque raccordée au conteneur évidé de manière à recouvrir une partie ouverte du conteneur évidé, la partie de couvercle sétendant de la surface adhérente à la périphérie de la surface adhérente et une partie adhésive pour fixer la partie de couvercle et la surface adhérente.
