There are provided a sheet having a silicon/plastic bi-layer structure capable of easily transferring a paste even when a hard roll is used, the hard roll having excellent durability but having disadvantages that the paste is poorly transferred when the paste is printed on a plastic base, and a method for producing the same. The bi-layer structured sheet having excellent printability when printed by hard roll includes a flexible substrate and a silicon resin formed on the substrate.
