The present invention provides a proton conducting polymer which provides proton conductivity without humidification and is suitable for electrochemical device materials such as solid electrolytes for fuel cells and electrolytes for batteries. The proton conducting compound is produced by polymerization of a salt of a melamine compound represented by the following equation (2) and a Bronsted acid:
wherein, R1, R2, R3, R4, and R5 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; 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, acryl groups of 1 to 6 carbon atoms, acyloxy groups of 1 two 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; R6 is hydrogen or an alkyl group and n is an integer equal to or larger than 1,
