An improved flashing sheet suitable for the formation of a flashing seal at a non-flat part having a three dimentional shape is provided. The flashing sheet comprises a base sheet of knitted fabrics having a high expandability in all directions and a modified bitumen layer of a mixture of bitumen and rubbers. This flashing sheet can be easily and directly applied onto the non-flat part of a substrate without any complex procedures and also without causing water leakage problems of the flashing seal.
