PROBLEM TO BE SOLVED: To provide a practical microneedle preparation which solves the problem of a drug residue being generated on the stratum corneum.SOLUTION: In a microneedle array, a needle length is 350 μm or more and 900 μm or less, and the diameter of the apex of a needle tip end portion 1 is 20 μm or more and 100 μm or less. The microneedle array has a drug application portion, and has a bio-insoluble polymer as a base. In the microneedle array, a lower edge of the drug application portion is 200 μm or more from a root of the needle.SELECTED DRAWING: Figure 1【課題】角質層に薬剤残りが発生する問題点を解決し、実用的なマイクロニードル製剤を提供する。【解決手段】針長さは３５０μｍ以上９００μｍ以下であり、針先端部１の頂点の直径は２０μｍ以上１００μｍ以下であり、薬剤の塗布部を有し、生体非溶解性高分子を基剤とするマイクロニードルアレイであって、薬剤の塗布部の下端は針の根元から２００μｍ以上であるマイクロニードルアレイ。【選択図】図１
