MANUFACTURING METHOD OF MICROSTRUCTURE

摘要

A method for producing a microstructure according to the present invention comprises the following steps: providing a patch-producing sheet (30) having a bottom layer (34) formed in an upper side thereof to be exposed; providing the patch-producing sheet (30) on a first process substrate (50) and a second process substrate (30); providing spots of a viscous composition in a plurality of separated points on the bottom layer (34) of the patch-producing sheet (30) provided to the first process substrate (50) or provided to both the first process substrate (50) and the second process substrate (60); making the patch-producing sheet (30) provided to the second process substrate (60) or the viscous composition forming the spots on the patch-producing sheet (30) provided to the second process substrate (60), come in contact with the viscous composition forming spots on the patch-producing sheet (30) provided to the first process substrate (50); elongating the viscous composition by relatively moving the second process substrate (60) against the first process substrate (50), and coagulating the elongated viscous composition; and cutting the coagulated viscous composition. Process time consumed in producing the bottom layer which serves as a base on which a microneedle is produced may be remarkably reduced.
