An edible powder formed of particles smaller than a film thickness, a predetermined component, and an edible liquid having a mass 35% or less of a mass of the powder are kneaded to generate a plastic solid material containing a liquid. The solid material is extruded from a mold to plastically deform the solid material and a predetermined cross-sectional shape is imparted to the solid material. The solid material having the predetermined cross-sectional shape is sliced with a cutting edge so as to have a film shape having a predetermined thickness.

Method of producing edible film, film formulation, and edible film

Provided is an inexpensive microneedle array with little dimensional error that can control, with high precision, the amount of a predetermined component to be introduced to the inner part of the skin, and a production method for this microneedle array. A foundation that is insoluble or sparingly soluble in inner part of the skin is overlaid on a mold. A plurality of frustum-shaped protrusions, which are insoluble or sparingly soluble in the raw material liquid, provided on a first main surface of the foundation are fit into a plurality of cone-shaped recesses. The raw material liquid in the plurality of cone-shaped recesses dries and, as a result, a plurality of microneedles, which are dissolvable in the inner part of the skin, are fixed to tip surfaces of the plurality of frustum-shaped protrusions.

Microneedle array and method for producing the same

A product having a microneedle array is provided wherein the composition distribution has been adjusted with good accuracy. A droplet-delivery apparatus of a microneedle-array manufacturing apparatus is configured capable of delivering, to each recessed part, droplets of a raw-material liquid in a prescribed amount that is less than the capacity of the recessed part. An aligning apparatus can align the relative position of the droplet-delivery apparatus and a mold such that the droplets from the droplet-delivery apparatus are caused to land in each of the recessed parts. The droplet-delivery apparatus delivers a plurality of the droplets to each of the recessed parts; and the aligning apparatus aligns the relative position of the droplet-delivery apparatus and the mold such that a second droplet lands in each of the recessed parts on the center part side of a first droplet.

Microneedle-array manufacturing apparatus, microneedle-array manufacturing method, and product having the microneedle array

A method of manufacturing a conical-projections-sheet packaging body includes forming a plurality of conical-recess parts on a conical-projections forming sheet; forming, by supplying a conical-projections material to the conical-projections forming sheet, a conical-projections sheet including a base sheet and a plurality of conical projections formed on a surface of the base sheet and disposed inside the plurality of conical-recess parts; forming a plurality of sets of the conical-projections forming sheets and the conical-projections sheets by punching out the conical-projections forming sheets and the conical-projections sheets; and using a package member to package a set of the conical-projections sheets and the conical-projections forming sheets tightly adhered to one another. Thus, the plurality of conical projections of the conical-projections sheet are protected.
