Abstract
A molded article with improved mechanical strength properties and thermal properties, and a method for producing the molded article. A composite molded article (C) comprising a cellulosic nanomaterial (A) and a thermoplastic resin (B), an area under a stress-strain curve of the composite molded article (C) (AUC1) being at least two times an area under a stress-strain curve of a melt-molded article (D) having the same composition as that of the composite molded article (C) (AUC2), wherein the stress-strain curve is a curve drawn with strain (unit: %) on the horizontal axis and stress (unit: MPa) on the vertical axis and obtained by subjecting the composite molded article (C) or the melt-molded article (D) to a tensile test, and the area is an area up to the horizontal axis from under a curved portion of the curve that is from the origin (stress: 0) of the stress-strain curve to a fracture of the composite molded article (C) or the melt-molded article (D).
