An applicator comprises a transmission member, a housing guiding a reciprocation of the transmission member, and a cap covering the housing. The transmission member is provided with a stopper extending in a direction orthogonal to an axial direction thereof. An upper end of the housing is formed with a projection sliding the stopper. The inside of the cap is formed with a lead part. The stopper is slid by the lead part to an end part of the projection when the cap is pushed and thereafter disengages from the projection when the cap is further pushed, so that the transmission member transmits the biasing force of an elastic member to a microneedle. This enables the microneedle to be applied to a skin.本發明之微型針貼片施作器,係具備:傳達構件;及導引傳達構件之往復運動的外殼;以及覆蓋外殼的帽蓋。在傳達構件,係設置有延伸於與該傳達構件之軸方向呈正交之方向的止動件。在外殼之上端,係形成有用以使止動件滑動的凸部。在帽蓋之內側係形成有誘導部。當帽蓋被按壓時,止動件就藉由誘導部而滑動至凸部之端部,之後當帽蓋更進一步被按壓時,止動件就從凸部脫離,藉此使得傳達構件將彈性構件之彈壓力傳至微型針。藉此,可將微型針應用於皮膚。10‧‧‧施作器20‧‧‧本體30‧‧‧帽蓋330‧‧‧開口
