Provided are a gel sheet comprising a polymer, having a high water content, having high strength and being harmless to the body; a cosmetic moisturizing sheet providing comfortable touch feeling to the skin and exhibits good adhesion to the skin; and a preparation method of these sheets. More specifically, provided is a gel sheet comprising low-substituted cellulose ether having a molar substitution degree of from 0.05 to 1.0, water-soluble cellulose ether having a molar substitution degree of from 1.1 to 1.4 and water. Also provided is a method for preparing a gel sheet, comprising steps of casting an aqueous alkaline solution comprising low-substituted cellulose ether having a molar substitution degree of from 0.05 to 1.0 and water-soluble cellulose ether having a molar substitution degree of from 1.1 to 1.4 on a plate, coagulating the cast solution, and washing the cast coagulated solution.
