PROBLEM TO BE SOLVED: To provide a washing machine using CO2 gas as a household washing machine easy to be used. SOLUTION: Since the washing tub 2 of a washing machine 1 is opened to the atmospheric air, pressure is not applied to it, it can be easily used for household washing machine. A CO2 solution generating device 10 generates CO2 solution by leading the service water into a pressure container and leading CO2 gas in a gas cylinder into the pressure container. Fine bubbles of the CO2 gas atμm order is generated in the water in the washing tub 2 by supplying the CO2 solution to the water inside of the washing tub 2. Impact wave including the ultrasonic wave area and generated when the bubbles of the fine CO2 gas is broken eliminates the dirty in a clearance of the fiber.
