A non-humidified proton-conductive membrane according to the present invention includes a polymer and a proton-conductive substance. The polymer includes a glassy or crystalline first site having a glass-transition temperature or melting temperature higher than the service temperature of the proton-conductive membrane and a second site capable of forming a noncovalent bond. The proton-conductive substance includes a proton-releasing/binding site capable of noncovalently binding to the second site of the polymer and a proton coordination site capable of coordinating to protons, the proton-releasing/binding site and the proton coordination site being included in different molecules that interact with each other or being included in the same molecule. A proton-conductive mixed phase that includes the second site to which the proton-releasing/binding site of the proton-conductive substance is bound and the proton-conductive substance is lower than the service temperature of the proton-conductive membrane. The amount of the proton-releasing/binding site is excessively large compared with the amount of the second site of the polymer.
