Abstract

An absorbent film and a substrate having extremely simple production without having an adhesive layer that can generate volatile components. The absorbent laminate contains a substrate, which has an inorganic material or a low-thermal-contraction organic material, and an absorbent film on the surface of the substrate. The organic material of the substrate has a rate of thermal contraction in the direction of conveyance thereof when performing hot pressing by means of a heating roller under the conditions of 140° C., a roller pressure of 0.1 MPa, and a conveyance speed of 0.4 m/min of less than 0.6%. The absorbent film has an absorbent layer adhered to the surface of the substrate without an adhesive layer therebetween and containing less than 87 vol % and at least 25 vol % of a thermoplastic resin binder and over 13 vol % and no greater than 75 vol % of an inorganic absorption agent.
