A shaped article of collagen having 5 to 20 .mu.m of thickness, the peak maximum temperature of endothermic denaturation thereof being in the range of 62.degree. to 71.degree. C., the wet tensile strength thereof being in the range of 3 to 6 kg/mm.sup.2 and the wet tear strength thereof being in the range of 25 to 150 g.multidot.cm/cm is prepared by a process comprising cross-linking a collagenous material so that the difference of the peak maximum temperatures of endothermic denaturation of the material between before and after the cross-linking falls in the range of 1.0.degree. to 10.degree. C. and the peak maximum temperature after the cross-linking falls in the range of 63.degree. to 74.degree. C., fibrating the cross-linked collagenous material to prepare an aqueous dispersion with the viscosity of 100 to 2000 cP and the spinnability of 30 to 80 mm at the concentration of 1% by weight of collagen fiber and subjecting the dispersion to electrodeposition.
