PROBLEM TO BE SOLVED: To provide a novel polystyrene resin foam which maintains a beautiful streaked pattern with high designability and has excellent antistatic performance, and can also be produced conveniently and inexpensively.SOLUTION: A polystyrene resin foam 1 has a polystyrene resin foam layer 2. On at least one face of the foam layer 2, streaked antistatic layers 3 are placed, the antistatic layers 3 comprising antistatic agent. The foam has a surface resistivity (A) of 1×10&OHgr; to 1×10&OHgr;, and an interval between the streaked antistatic layers is 20 mm or less. |
