PROBLEM TO BE SOLVED: To provide a transdermal absorption sheet capable of reducing a drying time and capable of suppressing diffusion of a chemical, and a transdermal absorption sheet.SOLUTION: A first polymer solution 54 containing a chemical is dripped into a mold 50 in which needle-shaped recesses are formed, and dried to form a first polymer layer 11 containing the chemical, in at least part of the needle-shaped recesses. A second polymer solution 58 without the chemical is dripped into the mold 50 in which the first polymer layer 11 is formed, and semi-dried to make a second polymer layer 12. A sheet 3 is placed on the second polymer layer 12, and the second polymer layer 12 and the sheet 3 are pressed and dried to form a needle-shaped array sheet including the first polymer layer 11, the second polymer layer 12 and the sheet 3. Then, the needle-shaped array sheet is separated from the mold 50. A transdermal absorption sheet 10 is manufactured in this way. |
