Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an in-vivo degradable absorbable filament laminar body having shape-holding property and strength at the same time. SOLUTION: The filament laminar body is obtained by the following processes: an in-vivo degradable absorbable polymer having a viscosity average molecular weight of 50,000-600,000 is dissolved in a solvent; the polymer solution is discharged from nozzles into filaments; the resulting filaments are piled up by entangling and fusing; and the solvent is vaporized to solidify the piled filaments.
