Document Type and Number:
WIPO Patent Application WO/2023/190911
Kind Code:
A1
Abstract:
A microneedle structure 10 equipped with needle-shaped parts 12 having a hole formed therein and a substrate 11 provided with said needle-shaped parts on one surface thereof. The needle-shaped parts 12 have a porous structure formed therein, and the value of the tip strength of the needle-shaped parts 12 is 40mN or higher. This method for producing a microneedle structure produces said microneedle structure 10. As a result, it is possible to provide: a microneedle structure having needle-shaped parts for which loss thereof and damage thereto is suppressed during use; and a method for producing said microneedle structure.
