This invention provides a waterproof and moisture-permeable fabric which prevents to lower in a water pressure resistance, repetitively washed. The waterproof and moisture-permeable fabric consists of a body of a fabric and a microporous film of mainly polyurethane which is laid on the body. The microporous film contains 1 to 9 mass % of fluorinated water repellent agent, 0.1 to 2 mass % of oil-soluble fluorinated surfactant and if necessary 3 to 45 mass % of fine silica powders. The waterproof and moisture-permeable fabric is obtained by the following method. After coating a resin compound on the surface of the body, the resin compound is dipped in a coagulating bath to form the microporous film. The resin compound dissolves or disperses mainly polyurethane, 1 to 9 mass % of fluorinated water repellent agent, 0.1 to 2 mass % of oil-soluble fluorinated surfactant and if necessary 3 to 45 mass % of fine silica powders in N,N-dimethylformamide. The coagulating bath is an aqueous solution containing less than 30 mass % of N,N-dimethylformamide.
