    Abstract: A method of producing a transdermal absorption sheet includes: filling needle-like recessed portions on a mold having the needle-like recessed portions with a polymer solution; drying the filled polymer solution to form a polymer layer; and peeling off the polymer layer, wherein, in drying the polymer solution, low rate drying conditions are set in a concentration range in which an average solid content concentration of the polymer solution is 70 wt % to 80 wt %. When a constant drying rate of water is used as an index, in the concentration range in which the average solid content concentration of the polymer solution is 70 wt % to 80 wt %, and the constant drying rate is lower than a maximum value of a constant drying rate under a drying condition where the average solid content concentration of the polymer solution is less than 70 wt % and more than 80 wt %.

    Abstract: A nanoimprinting mold includes: a mold main body having a fine pattern of protrusions and recesses on a surface thereof; and a mold release layer formed on the surface of the mold main body. The mold release layer is formed within a mold release layer forming region, which is a region of the mold main body that includes a patterned region where the fine pattern of protrusions and recesses is formed and has an outer edge positioned outside the outer edge of the patterned region. An outer peripheral mold release layer has a thickness distribution in which the thickness of the outer peripheral mold release layer is locally maximal at positions outside the outer edge of the patterned region, substantially continuously along the entire periphery. Thereby, it becomes possible to restrict the region in which resist flows during nanoimprinting, without employing a mesa type substrate.

    Abstract: A resist layer constituted by a resist composition (which may include unavoidable impurities) including a polymerizable compound that includes polyfunctional monomers that become polymers having three dimensional structures by cross linking when polymerized and a polymerization initiating agent which is activated by one of light and an electron beam is formed on a substrate. A surface of a mold having a predetermined pattern of protrusions and recesses is pressed against the resist layer. Light is irradiated onto the resist layer to cure the resist layer. The mold is separated from the resist layer under conditions that the temperature of the resist layer is 40° C. or greater.

    Abstract: Provided is a method of manufacturing a microneedle array in which an active ingredient is concentrated at a tip while an active ingredient content is guaranteed. In order to achieve the object, a method of manufacturing a microneedle array in which needle-like recessed portions of a mold are filled with a liquid to form one dose of a patch includes determining a filling amount of the liquid from a difference in mass of the mold before and after filling of the liquid, determining a filling state of the liquid in the mold filled with the liquid, sucking the mold in which the filling amount and the filling state of the liquid are determined to be normal from a rear face, and evaporating and drying a solvent of the liquid of the sucked mold.

    Abstract: The method of producing a transdermal absorption sheet includes, in this order, a filtration step of carrying out sterile filtration on a base liquid, a base liquid feeding step of feeding the base liquid to a surface of a mold having needle-like recessed portions, tip ends of which are filled with a drug solution, while leaving a space between the drug solution and the base liquid, a drying step of drying the drug solution and the base liquid, and a peeling-off step of peeling off a formed transdermal absorption sheet in which an average concentration of solid contents of the base liquid in the drying step is increased by 5% by weight or more from an average concentration in the base liquid feeding step, and then in a state in which the average concentration is 75% by weight or less, the base liquid is moved into the needle-like recessed portions.
