PROBLEM TO BE SOLVED: To provide a method of producing a laminated sheet, capable of reduce distortion of a transillumination image.SOLUTION: A method of producing a laminated sheet 1 includes: a first curing step of, with the use of an impregnated material 11 where a glass cloth is impregnated with a transparent resin, irradiating the impregnated material 11 with ultraviolet rays to promote the curing of the transparent resin, and thereafter irradiating an impregnated material 11A with electron rays to cure the transparent resin, thereby obtaining a transparent composite sheet 10 that has a transparent resin-cured material where the transparent resin is cured and the glass cloth; a step of arranging a curing resin 21 on a surface of the transparent composite sheet 10; and a second curing step of irradiating the curing resin 21 with ultraviolet rays to promote the curing of the curing resin 21, and thereafter irradiating a curing resin 21A where the curing is promoted with electron rays to cure the curing resin 21A, thereby forming a coating layer 20 where the curing resin 21A is cured. |
