The present invention relates to a manufacturing method of cork film, stationery and a phone case using the cork film. The manufacturing method of the cork film comprises: (A) a step of collecting a cork bark from a natural cork hardwood; (B) a step of firstly drying the collected cork bark for 6 months to one year at room temperature; (C) a step of boiling the firstly dried cork bark by using a steam at 100°C-300°C; (D) a step of secondly drying the boiled cork bark for 10-40 hours at room temperature; (E) a step of forming a bulk cork board by adhering the secondly dried cork bark with each other; (F) a step of forming a cork board by cutting the bulk cork board as a constant standard; (G) a step of forming a cork film by compressed adhering the cork board on the upper side of an adhesive film after arranging the adhesive film on the upper side of the fabric film; (H) a step of forming a synthetic cork film by sewing the formed cork film on the upper side and lower side of a sponge fabric. The cork film according to the present invention is harmless to human body; and suitable for mass producing; capable of supplying in low price; has an excellent deodorizing function, antibiotic function and far-infrared radiation emitting function; is easy to use; and has a fancy aesthetic feature.
