Abstract: A method of manufacturing a formed body for an electrode includes a first step of dropping an electrode material containing an electrode active material into a gap between a pair of transport belts and introducing the electrode material between transport surfaces of the pair of transport belts; a second step of belt-transporting and pressurizing the introduced electrode material with the pair of transport belts; and a third step of transferring the electrode material after the belt transporting and the pressurization, on a deposition belt, in which a transport direction in a transport, passage through which the electrode material is transported, of the deposition belt intersects a transport direction in a transport passage, through which the electrode material is transported, of the pair of transport belts.

Abstract: Provided is a method of producing a microneedle array unit which is capable of suppressing damage to a microneedle array. The method of producing a microneedle array unit, including an array preparing step of preparing a microneedle array which includes a sheet and a plurality of needles arranged on one surface of the sheet; a container preparing step of preparing a container which includes an accommodating portion defining an opening and a space for accommodating the microneedle array, and a deformable portion disposed on a side opposite to the opening and integrated with the accommodating portion; an accommodating step of accommodating the microneedle array in the accommodating portion of the container by allowing the other surface of the sheet of the microneedle array and the deformable portion of the container to oppose each other; and a deforming step of deforming an outer surface of the accommodating portion inward, which is positioned between the one surface of the sheet of the microneedle array and the opening of the accommodating portion, to form a protrusion that reduces an area of the opening.

Abstract: Provided is a method for manufacturing a microneedle array, which enables efficient and stable manufacturing of a microneedle array including a needle-shaped protrusion having a constricted shape. The method for manufacturing a microneedle array includes: a first cutting step of forming a needle-shaped protrusion by cutting a base material by a first cutting tool; a second cutting step of forming a constricted shape in the needle-shaped protrusion by cutting a part of the needle-shaped protrusion by a second cutting tool different from the first cutting tool; a mold forming step of molding, from a plate precursor manufactured through the first cutting step and the second cutting step, a resin mold having a needle-shaped hole which has an inverted shape of the plate precursor; a first array manufacturing step of filling the needle-shaped hole of the resin mold with a drug solution and then drying the drug solution; a second array manufacturing step of filling the needle-shaped hole with a base material solution and drying the base material solution, after the first array manufacturing step; and a peeling step of peeling, from the resin mold, a microneedle array manufactured by the resin mold.
