PROBLEM TO BE SOLVED: To provide a waterproof none-woven fabric for a building such as a wall material, a roof material, or underroof material excellent especially in the peeling strength as an asphalt waterproof fabric and furthere, excellent in size stability in asphalt processing and process passable property. SOLUTION: A binder resin and a silicone base resin are simultaneously processed with impregnation processing to a nonwoven fabric on which a needle punch processing and/or a heat pressing process is applied on a long fibrer nonwoven fabric, thereby, a peeling strength by the single tungue method is 40N or larger in the vertical direction, 44N or larger in the lateral direction. A stress in 3% elongation of the vertical direction at 160°C is 40N/5 cm or larger. And a dry heat contraction rate at 180°C is 5.0 % or lower in both vertical/lateral directions.
