The intruder-proof (burglar-proof) security glass sheet has a polycarbonate glass sheet (4) between two silicate glass sheets (1 and 2). The cast glass sheet (1) has a smooth outer surface (1b) and an inner surface (1a) with a heavy structure. The other silicate glass sheet (2) has smooth surfaces (2a and 2b) on both sides. The polycarbonate glass sheet (4) also has smooth surfaces on both sides. It is bonded to the silicate glass sheets (1 and 2) without gaps by means of adhesive layers (3 and 5). In this way, it is possible to combine the advantages of silicate glass and plastic glass without the disadvantages thereof in the case of thin walls, and structuring is also possible. <IMAGE>
