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.
