PROBLEM TO BE SOLVED : To provide an aqueous solution of composite particle precursor which contains metal elements, precursors of composite particles, at a high concentration in a stable state in an aqueous solution and enables sufficiently fine composite particles having sufficiently high NOx treatment capability to be produced efficiently. SOLUTION : The aqueous solution of composite particles contains : a first compound containing at least one metal element selected from a group consisting of alkali metals and alkaline earth metals; a second compound containing at least one metal element selected from a group consisting of titanium, aluminum, zirconium, and rare earth metals; a third compound having multidentate ligand; a fourth compound containing at least one metal element selected from a group consisting of platinum, rhodium, palladium, gold, silver, copper, cobalt, iron, manganese, and nickel; and ammonia.
