| 摘要 |
The purpose of the present invention is to prevent warping of a microneedle sheet caused by the amount of moisture which the microneedle sheet absorbs from the skin differing between a sheet-shaped substrate and microneedles, as well as to prevent sweating of the skin, by having the amount of moisture absorbed by the microneedle sheet be greater than the amount of moisture diffused from the microneedle sheet. This microneedle patch (10) is configured to have a layered arrangement of a sheet-shaped substrate (12), a plurality of microneedles (11) upon the sheet-shaped substrate (12), and an adhesive sheet (14). The adhesive sheet (14) has a property of being moisture-permeable, and is layered on the opposite face of the sheet-shaped substrate (12) from the face of the sheet-shaped substrate (12) having the microneedles (11). |
