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.
