Abstract: Provided is a sheet-shaped mold possessing a high strength and having a low breakage rate in demolding even in a case where the mold is thin and has a large-area. The sheet-shaped mold is prepared by combining a cured silicone rubber containing a polyorganosiloxane and a fiber for reinforcing the cured silicone rubber. The fiber may comprise a cellulose nanofiber. The sheet-shaped mold may have an uneven pattern on at least one surface (or side) thereof. The fiber may be surface-treated with a hydrophobizing agent. The fiber may forma nonwoven fabric, and the nonwoven fabric may be impregnated with the cured silicone rubber. The cured silicone rubber may comprise a two-component curable silicone rubber having a polydimethylsiloxane unit. The sheet-shaped mold may be a mold for nanoimprint lithography using a photo-curable resin.
