PERCUTANEOUS ADMINISTRATION DEVICE AND METHOD OF MANUFACTURING PERCUTANEOUS ADMINISTRATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a percutaneous administration device capable of suppressing divergence of a quality evaluation value of a substrate including a water-soluble polymer material from a reference value, and a method of manufacturing the percutaneous administration device.SOLUTION: A percutaneous administration device 10 includes a substrate 11 and projection parts 12. The substrate 11 has: a poor water-solubility substrate 13 which includes multiple gaps 16 delimited by a structure constituting the substrate 13 and dispersed inside the substrate 13 and in which in a state where gaps 16 are released to the outside of the substrate 13, the substrate 13 has such a dimension as to pass a water-soluble liquid body containing the water-soluble polymer from a second surface 11T to a first surface 11S of the substrate 11; and a filling part 14 consisting of a material containing a water-soluble polymer and filling at least parts of the multiple gaps 16.SELECTED DRAWING: Figure 2
