As a paper-made stampable sheet having a high rigidity and, if necessary, improved adhesiveness and non-permeability and a light weight stampable sheet shaped body made from this sheet and a method of producing the same, there are proposed a paper-made stampable sheet obtained by paper-making a mixture of thermoplastic resin and reinforcing fibers to obtain a sheet-like web, piling a thermoplastic resin film of a single layer or multi layer or an organic fiber nonwoven fabric having at least one excellent property selected from rigidity, non-permeability and adhesiveness on at least one-side surface of the sheet-like web in accordance with use purpose, compressing them under heating above a melting point of the thermoplastic resin constituting the web, cooling and solidifying at a compressed state as well as a light weight stampable sheet shaped body made from this sheet and a method of producing the same.
