PURPOSE:To easily separate generated steam from water and improve the thermal efficiency by providing in the steam-generating device a porous material accommodated in a jacket, a heater, a feed water preheating passage, a feed water pipe and a steam lead out pipe which extend to the outside of the jacket. CONSTITUTION:When feed water introduced into a feed water preheating passage 4 from a water tank 35 via a feed water pipe 5 and a feed water pressure- delivery pump 9 passes a water-preheating part 4a and the feed water enters a water-preheating part 2a of the porous material 2 and permeates into the same water-preheating part 2a, the feed water is preheated with a heater 3 and enters an evaporating part 2b of the porous material 2. Upon this occasion, the feed water begins to boil and steam is generated. Further, generated steam is further heated, and is sent from a steam lead-out pipe 6 to a first adsorption tank 24 or a second adsorption tank 25 in the form of an overheated steam.
