Abstract: A heat-insulating sheet includes a fiber sheet having spaces therein and silica xerogel held in the spaces. The heat-insulating sheet includes a high-compressive region and a low-compressive region. A compression rate of the high-compressive region of the heat-insulating sheet with respect to a pressure of 0.25 MPa applied to the high-compressive region is greater than or equal to 30% and less than or equal to 50%. A compression rate of the low-compressive region of the heat-insulating sheet with respect to a pressure of 0.25 MPa applied to the low-compressive region is greater than or equal to 1% and less than or equal to 5%. This heat-insulating sheet has large thermal insulation as a whole.

Abstract: A method for manufacturing a gravure plate includes, setting a certain measurement area on a surface of the gravure plate, finding at least one of a spatial volume that is the total of the volume of a space formed by a plurality of cells located in the measurement area and an average depth obtained by dividing the spatial volume by a surface area of the measurement area, and adjusting, based on a relationship between at least one of the spatial volume and the average depth and an application thickness of a printing material after printing, at least one of the spatial volume and the average depth so as to fall within at least one of a specified value range for the spatial volume and a specified value range for the average depth determined in accordance with a target value range for the application thickness.
