METHOD FOR PRODUCING PINHOLDER-SHAPED MICRONEEDLES, AND MICRONEEDLE

WIPO Patent Application WO/2010/137319

A1

Provided is a method for producing a microneedle made of a resin. A method for producing a minute needle having a desired size wherein, using a liquid discharge device and multiple nozzles having a minute inner diameter, a molten resin is discharged to a base plate one or more times, and the attached molten resin is stretched to form a minute needle. The obtained minute needle of a microneedle has one or a plurality of resin layers, and the entirety of the layers are integrated to form an extension type minute needle. A method for producing a microneedle characterized in that a molten resin is discharged one or more times to a base plate, and the attached molten resin is stretched to form a minute needle, and a microneedle having characteristic minute needle obtained by this production method, are provided.
