A laminated fabric having air permeability and filtering properties. The laminated fabric is one obtained by laminating a protective layer to a supporting layer. The protective layer comprises a stretch nonwoven fabric formed from ultrafine fibers. The laminated fabric has an air permeability of 2 cc/cm<SUP>2</SUP>/sec or higher and a collection efficiency for 1-µm quartz dust of 90% or higher. The laminated fabric may further have a water-resistant layer disposed on the protective layer on the side opposite to the supporting layer.
