Provided is a front face sheet for an absorbent article having a peak-and-valley surface structure by which a body fluid can be smoothly transferred from the front face sheet to an absorbent without causing pooling or spreading of the body fluid on the front face sheet and which shows little back-flow of the liquid, induces no fear of leakage and is free from leakage. A front face sheet for an absorbent article having multiple welding-compressed parts, characterized in that the welding-compressed parts are located on the lowermost face in the thickness direction of the front face sheet and, on the back side of the front face sheet, the welding-compressed parts are surrounded by valleys or low-density sections having the lowest density within the front face sheets. The front face sheet for an absorbent article having these welding-compressed parts can be produced by locating a front face sheet between a member having multiple peaks and another member having multiple valleys capable of engaging with the preceding multiple peaks and then pressing the peaks into the valleys.
