摘要： The present invention provides a thin sheet with suppressed strain. The sheet according to the present invention has a thickness from 0.1 to 5 mm and is formed of a plastic that contains at least one resin selected from polyamide resins, polycarbonate resins, cellulose acrylate resins, and acrylic resins. A difference between a maximum value and a minimum value of retardation of the sheet is 3000 nm or less. The sheet according to the present invention can be obtained, for example, by subjecting a plastic containing at least one resin selected from polyamide resins, polycarbonate resins, cellulose acylate resins, and acrylic resins to extrusion molding to obtain a plastic in the form of a sheet, and subjecting the resulting plastic in the form of a sheet to vacuum forming, air-pressure forming, or vacuum air-pressure forming.
