PROBLEM TO BE SOLVED: To provide a puncture device for microneedles (including a microneedle array) that has minimized the possibility of a bend, damage, or breakage of the needles at the time of puncture.SOLUTION: A device 4010 for puncturing the skin with a needle 4003 of a microneedle patch 4001 includes a housing. The housing 4011 includes a support part 4014 for supporting the microneedle patch 4001, a pressure receiving part to which a user applies force to press the microneedle patch 4001 to the skin, and a plurality of leg parts having connection parts connected to the pressure receiving part 4012 at one end, and tip parts that come in contact with the skin at the other end. The housing is designed to be deformed when force is applied to the pressure receiving part 4012, and provide a "tension" 4202 to a part 4201 of the skin that is opposed to the support part 4014.SELECTED DRAWING: Figure 67【課題】穿刺時の針の曲がり,破損,又は折損の可能性を最小化したマイクロニードル(マイクロニードルアレイを含む)の穿刺装置を提供する。【解決手段】マイクロニードルパッチ4001の針4003を皮膚に穿刺する装置4010はハウジングを有する。ハウジング4011は,マイクロニードルパッチ4001を支持する支持部4014と,マイクロニードルパッチ4001を皮膚に押し付けるためにユーザが力を加えるための受圧部と,受圧部4012に連結される連結部を一端に有し且つ皮膚に接触する先端部を他端に備えた複数の脚部を有する。ハウジングは,受圧部4012に力が加えられると変形し,支持部4014に対向する皮膚部分4201に“張り”4202を与えるように設計されている。【選択図】図67
