4:

• A proton-conducting polymer composed of a polymer produced by the polymerization of a melamine compound salt obtained from a melamine compound represented by the following equation (2) and a Bronsted acid:

• R2 and R3 or R4 and R5 may join together to form a heterocyclic structure;
• and the alkyl group, the aryl group, and the heterocyclic group each may have a substituent selected from the group of alkyl groups of 1 to 6 carbon atoms, aryl groups of 6 to 12 carbon atoms, heterocyclic groups, an amino group, alkylamino groups of 1 to 6 carbon atoms, a nitro group, a carboxyl group, acyl groups of 1 to 6 carbon atoms, acyloxy groups of 1 to 6 carbon atoms, a cyano group, alkylsulfonyl groups of 1 to 6 carbon atoms, alkylsulfonyloxy groups of 1 to 6 carbon atoms, a sulfoxide group, a sulfonic acid group, alkoxycarbonyl groups of 1 to 6 carbon atoms, aryloxycarbonyl groups of 6 to 12 carbon atoms, aryloxy groups of 6 to 12 carbon atoms, and alkynyl groups of 2 to 6 carbon atoms;
