Provided is a waterproof breathable membrane (1) with which higher levels of both breathability and waterproof properties than in the prior art may be achieved. The waterproof breathable membrane (1) is provided with a nonporous resin film (2) in which are formed a plurality of through-holes (21a-21g) passing through in the thickness direction, and a liquid repellent layer (3) having openings (31) at locations corresponding to the plurality of through-holes (21a-21g) formed on a principal surface of the resin film (2). The through-holes (21a-21g) extend in linear fashion, and have diameter of 15 [mu]m or smaller, the hole density of the through-holes (21a-21g) in the resin film (2) being from 1 * 10<3>/cm<2> to 1 * 10<9>/cm<2>, inclusive. The through-holes (21a-21g) extend in directions inclined with respect to the vertical direction on the principal surface of the resin film (2), through-holes (21a-21g) of different directions being intermingled.
