Microneedle array having uneven needle density |
| abstract |
The present invention solves a problem that it is difficult for a microneedle located in a central portion of a microneedle array to be inserted into a skin. A microneedle array including a substrate and a plurality of microneedles arranged vertically and horizontally on one face of the substrate, wherein a needle interval of the microneedles is different in a peripheral portion and in a central portion of the substrate, and a needle density of the microneedles is different in the peripheral portion and in the central portion of the substrate. It is preferable that the needle density of the microneedles is sparser in the central portion than in the peripheral portion of the substrate, and the needle interval of the microneedles is wider in the central portion than in the peripheral portion of the substrate. |
