It is an object of the present invention to provide a proton-conducting membrane excellent in resistance to heat and durability and showing excellent proton conductivity at high temperature. It is another object of the present invention to provide a method for producing the safe and fuel cell using the same. The present invention provides a proton-conducting membrane, comprising an organic material (A), three-dimensionally crosslinked structure (B) containing a specific metal-oxygen bond, agent (C) for imparting proton conductivity, and water (D), wherein the organic material (A) has a number-average molecular weight of 56 to 30,000, and at least 4 carbon atoms connected in series in the main chain, and the organic material (A) and three-dimensionally crosslinked structure (B) are bound to each other via a covalent bond.
