A gelatin fiber and a gelatin film that are non-toxic and safe for a living body, have sufficient physical properties such as strength, elasticity, and flexibility, have high transparency, and have an appropriate stability to water, and these Providing inexpensive manufacturing methods for fibers and films. A method for producing a gelatin fiber, comprising spinning an aqueous solution containing gelatin and a polyhydric alcohol in air. A method for producing a gelatin film, comprising forming an aqueous solution containing gelatin and a polyhydric alcohol into a film in air. The obtained gelatin fiber / film is provided with a good balance of safety, mechanical properties such as strength, elasticity and flexibility, water resistance, and the like required for fish food, food casings, and medical materials.
