Abstract
The desalination apparatus according to the present disclosure includes: a water-repellent particle layer that is located below a water tank, contains water-repellent particles, and allows passage of water vapor generated by evaporation of the liquid stored in the water tank, the water tank being a space for storing the liquid; and a liquefying layer that is located below the water-repellent particle layer, and liquefies the water vapor that has passed through the water-repellent particle layer to obtain the fresh water. The water-repellent particle layer includes an anti-migration layer provided as a surface layer that faces the water tank and containing anti-migration particles. Each of the anti-migration particles has a higher aspect ratio than the water-repellent particles, the aspect ratio being a value obtained by dividing a length in a major axis direction by a length in a minor axis direction.
