Problem to be solved: to provide a paper felt felt improving durability.Solution: the base cloth 2 of the paper felt felt 1 is composed of a ground warp 8 and a ground warp 9, which is folded back to form a loop 6 and is woven into the ground weft 8 at the papermaking side, and the intermediate warp 9 which is woven into the ground weft 8 in the running surface side, and An additional warp 12 which is woven into the ground weft 8 on the traveling surface side of the upper section 10 is provided.The number of times the additional warp yarns 12 are woven so as to pass through the papermaking surface side relative to the ground weft 8 and the number thereof are the number of times that the intermediate step 11 made up of the ground warp 9 is woven so as to pass the papermaking surface side relative to the earth weft yarn 8, or less than half the number of the warp threads 8, and the additional warp yarns 12 constitute the lower section.The additional warp 12 is thicker than ground warp 9.Diagram
