Functional water

SUBJECT of the Invention The functional water which can prepare simply and has various functions is provided. PROBLEM to be solved The functional water whose total content of the salt of water， a polyvalent amine， and a polyvalent amine a polyvalent amine and/or its salt are contained as a function component， and is 95 weight% or more. As for the said polyvalent amine， it is desirable that it is an at least 1 sort(s) of compound selected from the group which consists of a polymer which has a structural unit derived from a specific polyamine and a specific cyclic amine， and a polymer which has a structural unit derived from specific unsaturated amine.
