PROBLEM TO BE SOLVED: To provide a liquid-permeable nonwoven fabric that is suitable for using for a body liquid treating product.SOLUTION: The liquid-permeable nonwoven fabric 31 is formed with thermoplastic synthetic fibers 30 and has protruding parts 25 extending in parallel with each other on an upper surface 21 in a lengthwise direction LD of the liquid-permeable nonwoven fabric 31. The protruding part 25 has a top part 26 and a skirt part 27. The thermoplastic synthetic fiber 30 includes a first fiber 41 and a second fiber 42. The first fiber 41 has a fineness in a range of 0.8-1.9 dtex and forms an upper part 43 in a thickness direction TD including an upper surface 21 in the thickness direction TD of the liquid-permeable nonwoven fabric 31, and the second fiber 42 has a fineness in a range of 2.0-6.0 dtex and forms a lower part 44 in the thickness direction TD including a lower surface 22 in the thickness direction TD. The fineness of the first fiber 41 is less than the fineness of the second fiber 42 by at least 0.5 dtex. |
