    Abstract: A manufacturing method for a laminated sheet comprises:coating a backing coating material on a base fabric (A) which is made of a material having a thermal deformation temperature of at least 150.degree. C., the backing coating material comprising(a) a resin aqueous emulsion and(b) 150-170 parts by weight of expandable styrene resin particles per 100 parts by weight of solids of the resin aqueous emulsion (a);stacking a base fabric (B) which is made of a material having a thermal deformation temperature of at least 150.degree. C. on the layer of backing coating material to form a laminate;compressing the laminate from at least one side so as to impregnate base fabric (B) with a portion of the coating material; andexpanding the expandable styrene resin particles and drying the resin aqueous emulsion by heating to a temperature which is higher than the softening point of the resin of the expandable styrene resin particles and which is lower than the thermal deformation temperature of base fabrics (A) and (B), thereby expanding the expandable styrene resin particles and forming a foam layer between base fabrics (A) and (B).
