Abstract: 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.

Abstract: 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.

Abstract: A light emitting and receiving module with heater is provided, which includes a base material. A light emitting and receiving element is disposed on the base material and performs at least one of light reception and light emission. A heater film includes an electrode formed on a base sheet. The heater film is formed so as to cover the light emitting and receiving element. A capacitance detection unit electrically connected to the electrode detects a floating capacitance between the light emitting and receiving element and the heater film. A power source electrically connected to the electrode heats the heater film. A control board switches the connection with the electrode between the capacitance detection unit and the power source.

Abstract: 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.

Abstract: 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 ?m and 100 ?m inclusive.

Abstract: 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.
