An embossed sheet, on which fine embossed patterns are regularly formed on a surface, is manufactured without any defects and with a high quality at a high line speed and at a high level of productivity. A method for manufacturing an embossed sheet, in which irregularities of a surface of an emboss roller is formed by transfer on a surface of a flexible strip-shaped sheet W. After coating a resin solution which is diluted with an organic solvent, the sheet on which a resin solution layer is formed on a surface is continuously run, the organic solvent contained in this resin solution layer is dried, the sheet after dried is wound around the emboss roller which is rotating, and irregularities of a surface of the emboss roller are transferred to the resin solution layer, and then the resin solution layer is cured, with the sheet being wound around the emboss roller.

In a microneedle sheet having a microneedle array composed of a large number of microneedles Formed on the surface of the sheet, the ridge lines or conical plains of the microneedles are curved inward into said microneedles. Since the ridge lines or conical planes of the microneedles have a shape curved inward into the microneedles, a microneedle sheet that can be smoothly inserted into the skin can be provided.

Polymer polysaccharide is added to a PVA coating liquid so that a density of the polymer polysaccharide is within the range between 0.05% and 0.5% by weight with respect to the PVA coating liquid. Next, a coating liquid layer is formed on a web by coating the web with the PVA coating liquid to which the polymer polysaccharide is added so that a temperature of the PVA coating liquid is within the range between 20° C. and 40° C. at the coating. Then, the coating liquid layer on the web is dried after it is preliminarily dried so that a temperature of the coating liquid layer is maintained at a temperature that is 3° C. lower than the temperature of the PVA coating liquid or lower for three seconds or more.

An improved method for forming a multilayer sheet or multilayer film and an improved forming die apparatus, include making the thickness of the multilayer sheet or multilayer film uniform along the width. In the forming die apparatus, an elastic choke bar is disposed in a passage of the melted resin along the width of the passage. A plurality of bolt members are arranged to abut against the choke bar. The choke bar is pushed and pulled by each bolt member, and a part of the choke bar corresponding to the bolt member is bent with regard to the passage. Thereby, the clearance along the width of the passage can be adjusted for every bolt member.

This invention provides a surface processing mask having a film mask and a method for manufacturing the same. In the film mask, particles are present as a single layer without overlapping with each other or particles containing first particles and second particles having etching resistance lower than that of the first particles are contained. Moreover, the invention provides a surface processing method including disposing the film mask on the front surface of a process target, and etching the front surface to form irregularities and an optical device having a substrate processed by the surface processing method. Moreover, the invention provides a particle-containing film in which particles are arranged to form a single layer without overlapping with each other and a method for manufacturing the same.

A method of fabricating a template (14) for a concave array mold (30) having a plurality of recesses of a high aspect ratio includes arranging a plurality of needles (10) in a mutually separated state and fixing the plurality of the arranged needles (10). This method allows a template for a concave array mold having a high aspect ratio structure to be easily and inexpensively fabricated. Further, the thus fabricated template can be used to easily and inexpensively fabricate a concave array mold. Furthermore, a needle array sheet can be fabricated by injecting and fixing a resin solution into the concave array mold (30) and separating the cured resin solution from the concave array mold (30).
