PROBLEM TO BE SOLVED: To provide a deaerator of single barrel type capable of subjecting feed water and steam to rectangular contact and enhancing deaeration efficiency even when being disposed on the under side of a feed water supply part which supplies feed water from the above side to a water storage part in a barrel. SOLUTION: The feed water supply part 3 includes: a feed water ejector 31 which ejects feed water from the above side to the water storage part 6; and a regulator which directs the feed water ejected from the feed water ejector 31 to a horizontal direction center part perpendicular to the axial direction of the barrel, a steam supply part 4 is configured to have a plurality of steam jetting unit groups 43 in the axial direction of the barrel 2, each steam jetting unit group 43 includes a plurality of steam jetting units which jet steam into the water storage part, in the horizontal direction perpendicular to the axial direction of the barrel 2 and the ejection means constituting the ejector group is arranged by setting a distance of a gap from the lower end position of each ejector to a barrel inner peripheral surface of the vertical direction lower side into the distance where the feed water can flow, and the ejector is prevented from being located on the horizontal direction center part vertical to the axial direction of the barrel 2.
