Provided is an applicator that holds a microneedle to facilitate puncture of the skin, and enables close adhesion, with an adhesive sheet such as a tape and the like, of the microneedle puncturing the skin, even without touching with the hand. In the present invention, it was found that puncture of the skin with a microneedle is facilitated and the microneedle can be fixed to the skin in close adhesion, by using an ingot-shape assisting tool as a table to hold a microneedle, and placing an adhesive sheet such as a tape and the like on the side face of the assisting tool.
