Abstract:
A method of manufacturing a structure having fine ribs, comprising:(a) preparing a composite sheet which comprises an elastic surface layer and a base layer with a higher rigidity than the surface layer, the surface layer having grooves arranged in a two-dimensional pattern, a depth of the grooves being shallower than a thickness of the surface layer, the surface layer being made of rubber and having a thickness falling within a range of 0.3 mm to 1 mm and the base layer being formed of a metal sheet having a thickness falling within a range of 0.2 mm to 0.5 mm;(b) filling the grooves of the surface layer with a paste material;(c) curing the paste material to form ribs;(d) laminating a substrate to the surface layer of the composite sheet, and pressing the composite sheet against the substrate from the base layer side by using a press roll, thereby compressing the ribs and adhering them to the substrate; and(e) removing the ribs and the substrate from the composite sheet.
