1. A method for producing a press-molded body of a polycarbonate sheet including a resin layer (A) containing a polycarbonate resin as a main component, and a resin layer (B) containing a high hardness resin (B) as a main component and a hard coat layer (C) sequentially stacked on at least one surface of the resin layer (A), the method comprising:
pre-heating the polycarbonate sheet to a temperature in the range of a glass transition point of the resin layer (A)−45° C. or higher and the glass transition point or lower;
locating the pre-heated polycarbonate sheet between an upper die and a lower die of a metal mold, wherein a time period after the pre-heating of the polycarbonate sheet is finished until the polycarbonate sheet is located between the upper die and the lower die of the mold is 90 seconds or shorter; and
clamping the mold to press one of the upper die and the lower die to the other of the upper die and the lower die to obtain the press-molded body of the polycarbonate sheet, wherein the mold has a temperature that is the glass transition point of the resin layer (A) or lower.
