Abstract

An object of the present invention is to provide a co-extruded laminated foam and a molded article using the foam having high durability and sufficient antistatic effects, and being superior to impact resistance, mechanical and physical property as to rigidity etc., buffering capacity, and thermoforming capability. The co-extruded laminated foam comprising a polyolefin resin layer which includes an antistatic additive and is laminated on at least one surface of a polystyrene resin foam layer having an apparent density of 100g/L to 450g/L and an open cell content of less than or equal to 40%, a polystyrene resin composition constituting the polystyrene resin foam layer includes a styrene elastomer, and an amount of a rubber component in the polystyrene resin composition is 9 to 30 weight % and a surface of the polyolefin resin layer of the co-extruded laminated foam after washing thereof by ethanol solution has a surface resistivity of less than or equal to 1x10<SP>13</SP>Ω.
