<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a needle-like body with little stimulation to the skin by securing the structural stability in a microneedle in the needle-like body by a sufficiently thick pedestal, and applying sufficient water vapor permeability to the pedestal. <P>SOLUTION: The method of manufacturing the needle-shaped body includes: a pretreatment step of making the resin contain a low-molecular-weight component with a lower boiling point or sublimation point than the melting point of resin; and a step of molding the pretreated resin into the needle-like body having the microneedle and the pedestal by the pressurization process between a duplicate plate and a support plate facing the same, and transferring bubbles within the resin to the pedestal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
