PROBLEM TO BE SOLVED: To enhance drying efficiency by adding a drying promoting function to warm-air drying, in a drying process of a washing/drying machine. SOLUTION: A sprayed coating film 4, which is composed of a far-infrared radiator, is formed on an inner surface of an inner lid 3 of the washing/drying machine, so that the drying efficiency can be enhanced. The coating film is formed, particularly, by using thermal spraying, so that a coating thickness can be made small and so that the production cost of the far-infrared radiator can be reduced. The use of coal combustion ash as a material for the far- infrared radiator can bring about not only a reduction in material cost but also the effective utilization of waste. Additionally, the sprayed coating film 4, which is composed of the far-infrared radiator, is heated with a heater unit 34 which is installed in the inner lid 3, so that far-infrared radiation from the far-infrared radiator can be increased.
