Abstract
Provided are: a laminated resin sheet for molding, which is less likely to cause an abnormal appearance during molding, and has an anti-glare layer but has excellent transparency; and a molded article using the same. This laminated resin sheet for molding comprises: a high-hardness resin layer containing a high-hardness resin; a base material layer which contains a polycarbonate resin (a1) and is disposed on one surface side of the high-hardness resin layer; and a hard coat anti-glare layer disposed on the other surface side of the high-hardness resin layer, wherein the glass transition point (Tg1) of the high-hardness resin and the glass transition point (Tg2) of the polycarbonate resin (a1) satisfy the following relationship, and the maximum valley depth (Rv) of the recesses and protrusions of the hard coat anti-glare layer is at most 0.9 μm −10° C.≤(Tg1−Tg2)≤40° C.
