Abstract
A method for manufacturing a hollow needle-shaped body includes producing a needle-shaped body having a substrate and a projection on a first surface of the substrate, and applying a laser beam to a second surface of the substrate opposite to the first surface such that a through hole that penetrates through the substrate and the projection is formed. The substrate and the projection are comprised of crystallized polyglycolic acid.
