PROBLEM TO BE SOLVED: To provide a moisture-permeable waterproof fabric having sufficient stereoscopic appearance and design on a moisture-permeable waterproof layer. SOLUTION: The moisture-permeable waterproof fabric is produced by laminating and bonding a cloth, an adhesive layer, a highly foamed layer and a moisture-permeable waterproof layer in the order. The highly foamed layer is composed of a thermally expanded microcapsule, a synthetic resin to keep the microcapsule on the inner face of the moisture-permeable waterproof layer and a hydrophilic microporous silica fine powder on the surface of the microcapsule or in the synthetic resin. The moisture-permeable waterproof fabric having the highly foamed layer can be produced by forming a moisture-permeable waterproof layer on the surface of a releasing material, applying a synthetic resin solution containing a thermally expandable microcapsule and a hydrophilic and microporous silica fine powder to the surface of the moisture-permeable waterproof layer, drying the applied solution to form a synthetic resin layer, laminating and bonding a cloth to the synthetic resin layer interposing an adhesive layer, and expanding the thermally expandable microcapsule by heating the product.
