A method for producing a retardation film comprising the steps of: co-extruding or simultaneously casting a thermoplastic resin A and a thermoplastic resin B to obtain a laminated film comprising a layer of the thermoplastic resin A and a layer of the thermoplastic resin B; and uniaxially stretching the laminated film at least twice to cross a molecular orientation axis in the layer of the thermoplastic resin A and a molecular orientation axis in the layer of the thermoplastic resin B each other at almost right angles.

The multilayer foam sheet has a surface resistivity of 1?1013? or less and has a foam layer and resin layers that are laminated on both surfaces of the foam layer. The resin layers each have a multilayer structure formed from a surface layer and an intermediate layer that is positioned between the surface layer and the foam layer. The foam layer includes a polyethylene-based resin PE2. The intermediate layers are configured from an antistatic mixture containing a polyethylene-based resin PE3 and a polymeric antistatic agent. The surface layers are configured from a mixed resin containing a polyethylene-based resin PE4 and a polystyrene-based resin, and substantially do not contain the polymeric antistatic agent. The polystyrene-based resin content of the mixed resin is 3-35 wt %.

A method for producing a vehicle seat member (30) in which a frame member (20) having protrusions (23, 25) is integrally molded to a foamed resin molded body (10) with high dimensional accuracy is provided. The method comprises an in-mold foam molding step of placing the frame member (20) in a mold (100), packing prefoamed resin particles, and molding the foamed resin molded body (10) by in-mold foam molding; and a demolding step of removing the mold (100) to obtain the vehicle seat member (30), wherein in the in-mold foam molding step, the foamed resin molded body (10) is molded so that (BA)/B is 13/1000 or less, wherein A is an outer dimension of the foamed resin molded body (10) in the vehicle seat member (30) obtained by the demolding step and B is an inner dimension of the mold (100) corresponding to the outer dimension.
