STAMPER FOR MICRONEEDLE SHEET, AND MANUFACTURING METHOD FOR THE SAME, AND MANUFACTURING METHOD FOR MICRONEEDLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To solve the problem that although a microneedle sheet is manufactured by injecting a needle material into a stamper for which recess sections are formed on a base material, the recess section of the stamper is extremely small, and therefore, a section where the needles cannot be formed because air has not been removed is generated.

SOLUTION: On the bottom of the recess section of the stamper of the microneedle sheet, a through-hole which penetrates the base material is bored. Air is removed by the through-hole, and the microneedle sheet filled with the needle material to the bottoms of the recess sections can be obtained.
