Abstract
A microneedle array which consists from small needles compared to a conventional metal injection needle is expected as a low invasive transdermal medical treatment device, and many fabrication approach have been conducted. In this study, we fabricated polymer hollow microneedles of one row by a fabrication method based on the combination of injection molding and microbonding techniques. Subsequently, the tilted needle array was fabricated by arranging these microneedles of one row aslant into the holder. We punctured the tilted needle array to silicone rubber by using the slideguide (surface plate). As a result, the high performance of the tilted puncture system was confirmed.
