To provide a composite sheet for a pinball game machine face plate, high in adhesive strength of a protective film, having excellent cutting machinability and furthermore excelling in antistatic properties when peeling the protective film from an acrylic resin plate.

The composite sheet for the pinball game machine includes: the acrylic resin plate containing acrylic resin and acrylic rubber particles; and the protective film provided on the surface of the plate. The content of the acrylic rubber particles in the acrylic resin plate is 15-70 pts.wt. based on 100 pts.wt. of the acrylic resin and acrylic rubber particles in total, and the surface resistivity (A) of one surface of the acrylic resin plate is 10⁸-10¹³ Ω/SQUARE. The protective film which is a laminate of a base material layer and an adhesive layer, is attached to the one surface. The adhesive layer contains a styrene-based block copolymer, and the thickness of the protective film is 0.04-0.25 mm.
