Disclosed is a medical material manufactured using collagen and a method of manufacturing the same. The method includes (1) preparing collagen using distilled water as a solvent, (2) filling a syringe with the prepared collagen and then spinning the collagen through a syringe needle, (3) immediately immersing the spun collagen in a cross-linking solution, which is a mixture including therein a hyperosmotic agent and a cross-linking agent mixed with each other, (4) removing and then washing the collagen after cross-linking is completed, and (5) removing and then drying the collagen after the washing is completed. When the collagen is spun and processed into the form of a thread and the spun thread is then cross-linked, the cross-linked collagen thread has increased strength compared to before cross-linking, and the shape thereof is retained in an aqueous solution."
