摘要: A vapor separator in an embodiment is arranged between a first space and a second space, and is used to allow vapor existing in the first space to permeate in the second space by making a vapor pressure in the second space lower than a vapor pressure in the first space. The vapor separator in the embodiment includes: a porous body including a first face in contact with the first space and having a convexo-concave structure, a second face in contact with the second space, and fine pores passing to the second face from at least wall of the first face which constitutes the convexo-concave structure; and water existing in the fine pores of the porous body.
