Abstract:
PROBLEM TO BE SOLVED: To provide a percutaneous administration device capable of increasing a drug injection dose into a skin.SOLUTION: The percutaneous administration device includes: an administration part that includes a substrate having a substrate surface 21S, and a projection part 22 projecting from the substrate surface 21S, the projection part 22 having a flow passage inside the projection part 22, opened to a peripheral surface of the projection part 22; and a support body 30 including a plurality of support parts 31 coming into contact with an administration object. Viewed from a direction facing the substrate surface 21S, the plurality of support parts 31 are mutually spaced from adjacent support parts 31 and enclose the substrate surface 21S, with a gap formed between the substrate surface 21S and the support parts 31. The administration part and the support body 30 are so configured as to displace the projection part 22 relative to the support parts 31 along a direction of extending to the projection part 22, from a position in a space enclosed by the plurality of support parts 31 to a position outside the space.SELECTED DRAWING: Figure 2
