A distillation apparatus which can be automatically replenished with a liquid, does not require a large amount of energy and can be produced at suppressed facility cost is provided. A distillation apparatus 100 for generating distilled water by use of solar heat 72 includes a heat transmissive window 10 that transmits the solar heat 72; a housing 20 that secures the heat transmissive window 10; and a heat absorber 25 that is located in the housing 20 and absorbs the solar heat 74 transmitted through the heat transmissive window 10. The housing 20 includes a first chamber 21 in which the heat absorber 25 is located; and a second chamber 22 connected to the first chamber 21 via a water vapor permeable membrane 40 that allows permeation of water vapor 64 generated in the first chamber 21. An intake opening 50 through which a liquid is introduced is provided below the first chamber 21. A water level adjustment mechanism 30 that adjusts a water level L of the liquid 63 covering the heat absorber 25 is provided in the first chamber 21.
