A collagen is extracted and produced from a raw fish skin through the steps: a salt admixing step for admixing a salt (e.g. NaCl, KCl or the like) with raw fish skin so as to allow non-collagen substances or portions (including fats and tissue portions other than collagen portions) to be removed from the fish skin, while simultaneously degreasing and deodorizing the skin under the salt effect; a salt removal step for causing the admixed salt and non-collagen substances or portions to remove from the skin, achieving the fats removal and deodorization; a collagen extraction step for extracting a collagen (gelatinous) from the this-treated skin; and a filtration step for filtering and refining the extracted collagen so as to obtain a refined collagen. The refined collagen may be dried and solidified. Thus, since inexpensive salt is used for effective removal of non-collagen substances or portions to obtain a collagen portion, the method itself is simplified and economical. Further, the fish collagen obtained thereby, be it fluid or dried, is of a highly refined property, i.e., colorless, odorless and degreased, which is suitable for food product elements and various industrial uses.
