The objective of the present invention is to provide a microneedle array which is configured of a sheet part and a needle part, and which is capable of achieving high medicinal effect. The present invention provides a microneedle array which comprises a sheet part and a plurality of needle parts that are present on the upper surface of the sheet part. The needle parts contain a water-soluble polymer and a medicament and 50% by mass or more of the total solid content of the needle parts is composed of the water-soluble polymer. In a needle tip region, which includes the needle tip of each needle part and has a height corresponding to 20% of the total height of each needle part, the water-soluble polymer and the medicament are present at a mass ratio of formula 1. The sheet part contains a water-soluble polymer.formula 1(Water-soluble polymer):(medicament) = 0.05-0.9:1
