wherein R 2, R 3, R 4 and R 5 each is independently an alkyl group, an aryl group, a heterocyclic group, or hydrogen and at least one of them is an alkyl group, an aryl group, or a heterocyclic group; R 2 and R 3 or R 4 and R 5 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; R 6 is hydrogen or an alkyl group and n is an integer equal to or larger than 1.
  2. A proton-conducting polymer as described in claim 1, wherein R 2 is hydrogen or R 2 and R 4 are hydrogen.
  3. A proton-conducting polymer as described in claim 1, wherein the said polymer the (M-B salt) is produced by the polymerization of the melamine compound salt (M-B salt) and a crosslinking agent having two or more radically polymerizable functional groups that are copolymerizable with the said melamine compound salt.
  4. A proton-conducting polymer as described in claim 3, wherein the amount of the crosslinking agent to be used is 0.1 to 50 wt% of the sum of the melamine compound salt and the crosslinking agent.
  5. A proton-conducting polymer as described in claim 4, wherein the crosslinking agent is an acrylic acid derivative having two or more radically polymerizable functional groups.
  6. A method for producing the proton-conducting polymer described in claim 4, which comprises treating a triazine compound represented by the following formula (3) with an aminoalcohol to give a melamine derivative represented by the following formula (4), treating the melamine derivative with an acrylic acid derivative represented by the following formula (5) to give a melamine compound represented by formula (2), reacting the melamine compound with a Bronsted acid to give a melamine compound salt, and polymerizing the melamine compound salt:

in formula (3), X is a halogen atom and R 2, R 3, R 4 and R 5 have the same meaning as in formula (2);

in formula(4), n is an integer equal to or larger than 1 and R 2, R 3, R 4 and R 5 have the same meaning as in formula (3);
