摘要： To protect a plurality of conical projections of a conical-projections sheet. A method of manufacturing a conical-projections-sheet packaging body 1 including: a step of forming a plurality of conical-recess parts 34b on a conical-projections forming sheet 34; a step of forming, by supplying a conical-projections material to the conical-projections forming sheet 34, a conical-projections sheet 23 including a base sheet 23a and a plurality of conical projections 23b formed on a surface of the base sheet 23a and disposed inside the plurality of conical-recess parts 34b; a step of forming a plurality of sets of the conical-projections forming sheets 34 and the conical-projections sheets 23 by punching out the conical-projections forming sheets 34 and the conical-projections sheets 23; and a step of using a package member 5 to package a set of the conical-projections sheets 23 and the conical-projections forming sheets 34 tightly adhered to one another.

摘要： A microneedle patch with which a treatment is reliably completed in a short time when a microneedle is administered into skin or mucous membrane is provided. A microneedle patch (100F) includes a base member (101) and a plurality of microneedles (103g) supported by the base member (101). Each microneedle (103g) includes a top-section layer (104) comprising a biologically active substance to be inserted in dermis (310), and an intermediate layer (106) provided between the top-section layer (104) and the base member (101), having a composition having breaking strength weaker than breaking strength of a composition of the top-section layer (104), and having a thickness of 5 µm and 100 µm inclusive.
