Abstract
Provided is a method for manufacturing a transdermal absorption sheet which makes it possible to manufacture a transdermal absorption sheet with a stable shape. The method for manufacturing a transdermal absorption sheet includes a step of forming a drug layer () on needle-like recess portions () of a mold () having the needle-like recess portions (), a step of supplying a polymer layer forming solution () to the inside of a step portion () of the mold (), a step of drying the polymer layer forming solution () so as to form a polymer layer () and a transdermal absorption sheet (), and a step of peeling off the transdermal absorption sheet () from the mold (). In the step of peeling off, pressing force is applied to a part of the step portion () in a second direction (B) opposite to a first direction (A) in which the transdermal absorption sheet () is released from the mold (), and the transdermal absorption sheet () is aspirated with a vacuum suction pad () from a side opposite to the mold () so that the transdermal absorption sheet () is peeled off from the mold () in the first direction (A).
