PROBLEM TO BE SOLVED: To efficiently cool heat-generating electronic parts scattered on a circuit board. SOLUTION: This washing machine is integrally provided with a water passage 33, through which water can be fed to a drum, above the unit case 17 of a power source unit 16. On the lower surface side of the water passage 33, the circuit board 31, on which the heat-generating electronic parts 30 are packaged, is installed by an engaging tool 32. By feeding water to the water passage 33 through a water feeding hose 15 in the case of feeding tap water, the heat-generating electronic parts 30 are cooled through the water passage 33.
