A heat insulating pad material, particularly for use in a battery shield, is made of a molded foam with a rough surface produced by in-mold expansion molding of expandable resin beads, a facing of a high-melting resin film, and an intermediate layer of a low-melting resin film. The foam and the facing are laminated together by melting the low-melting resin film in a manner that the rough surface is transparent through the facing. Upon lamination, heat may be applied onto the facing under pressure to emboss the rough surface of the molded foam, thus imparting a textured pattern. A heat insulating assembly for a battery comprises a battery case having outer surface walls and a pad of a one-piece pad member or pad members fayed and secured to the walls in a covering manner. The pad may be of the aforementioned pad material as well as molded foams produced by in-mold expansion molding or extrusion molding. The assembly may be secured by an additional fastening band, engagement of projecting members and recesses, splicing, etc.
