A molded article includes a hollow molded body formed of a base material and a heat insulating sheet member laminated to an outer surface of the hollow molded body. The base material is a blended material which contains about 50% by weight to about 90% by weight of a thermoplastic resin and about 10% by weight to about 50% by weight of an inorganic material, and has a flexural rigidity of at least about 1,350 MPa at 23.degree. C. and a flexural rigidity of at least about 550 MPa at 60.degree. C. A process for producing a molded article includes placing a heat insulating sheet member on a surface of a mold cavity of at least one mold half of separated mold halves, inserting a parison formed of a blended material having the above-described composition and flexural rigidity characteristics between the mold halves, clamping the mold halves, and introducing a pressurized fluid into the parison to inflate the parison in conformity with a shape of the mold cavity and bond the heat insulating sheet member thereto, to produce a molded article including a hollow molded body having a heat insulating sheet member laminated to an outer surface thereof.

[ What is claimed is:] [1.] A process for producing a molded article, comprising:placing a heat insulating sheet member on a surface of a mold cavity of at least one mold half of separated mold halves;inserting a parison between said mold halves, said parison being comprised of a blended material including about 50% by weight to about 90% by weight of a thermoplastic resin and about 10% by eight to about 50% by weight of an inorganic material having a heat conductivity which is significantly higher than that of said thermoplastic resin, material having a flexural rigidity of at least about 1,350 MPa at 23.degree. C. and a flexural rigidity of at least about 550 MPa at 60.degree. C.;clamping said mold halves; andintroducing a pressurized fluid into said parison to inflate said parison in conformity with a shape of said mold cavity and bond said heat insulating sheet member thereto, whereby a molded article comprising a hollow molded body having a heat insulating sheet member laminated to an outer surface thereof is produced.
