Summary:PROBLEM TO BE SOLVED: To provide a urea water storage device greatly reducing cost required for a countermeasure against freezing of urea water. SOLUTION: In the storage device of urea water 2 to be added as reducer to a selective reduction type catalyst for reduction conversion of NOx, a water feeding hose 5 with an electric heater 5a is inserted in a tank 1 storing the urea water 2 downward from an upper part and is extended to a tank 1 bottom part, a section to sink under the urea water 2 in the tank 1 of the water feeding hose 5 is covered by a long and narrow suck shape filter 8, and the filter 8 is thawed out by heat generated by the electric heater 5a of the water feeding hose 5.
