PROBLEM TO BE SOLVED: To provide a microneedle that can give good use feelings.SOLUTION: A microneedle includes a substrate having a first surface and a second surface, and a protrusion formed on the first surface of the substrate. Sound is generated when the substrate is pressed from the second surface to the first surface with force of predetermined magnitude or more. The substrate is curved in a recessed shape from the first surface to the second surface. When the substrate is pressed from the second surface to the first surface with force of predetermined magnitude or more, the substrate may change so as to be curved in a recessed shape from the second surface to the first surface and sound may be generated.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】使用感のあるマイクロニードルを提供する。【解決手段】第１の面および第２の面を備える基板と、基板の第１の面に形成された突起部とを含むマイクロニードルであって、基板を第２の面から第１の面に向かって所定以上の大きさの力で押圧した際に、音が発生する。また、基板が第１の面から第２の面に向かって凹状に湾曲し、基板を第２の面から第１の面に向かって所定以上の大きさの力で押圧した際に、第２の面から第１の面に向かって凹状に湾曲するように変化し、音が発生してもよい。【選択図】図１
