As shown in Figure 2, the lateral direction (X-direction) of the top sheet (2) dimensions from those of the lateral direction (X-direction) of the backing sheet (3) is small. The top layer (2) and the back layer (3) can be connected directly to each other or to another element. the outer peripheral part of the absorbent member (4), using a general adhesive or extending outward from its edge and thereby fixing the absorbent element (4) therein. are connected to each other using a fusing unit located within the extension.

As shown in Figure 1, the diaper (1) is a so-called open type diaper, Along both side face edges of the rear part (B), along the longitudinal direction (Y direction) A pair of fastening tapes (7 and 7) are provided and the 'front' (A) is at one tooth level (to the skin). the non-facing surface) is an adhesive tape (8) to fix the fastening tapes (7 and 7) has been provided. As shown in figures 1 and 2, on both sides of the diaper (1), along the longitudinal direction (Y direction), laterally (X direction) interior fixed at part (centre line (CL) side), extended in the Y direction, fixed a recovery layer (62) having a recovery elastic element (61) on its skin-facing surface, in the lateral portion of the topsheet (2) and on the side of the topsheet (2) in an extension portion of the backsheet (33) extending outward in the X direction from inserted and using a general adhesive or a fusing unit is fixed, thereby forming a pair of fixed retractors (TG and TG) (see Fig. 2). Moreover, The longitudinal direction on both sides of the diaper (1) as shown in figure 1= Along the (Y direction) outward from the elastic member 61 in the lateral direction (X) direction. a plurality of leg-resting elastic elements (63) extended in the Y-direction on the side leg retractors were created using With the (63) shrinkage, leg lifters (LG and LG) were formed. Also, Figure 1 = on one end of the diaper (1), on the back (B) side, as shown in the longitudinal direction (Y-direction) to form a waist retractor. The partially elastic member 64 is positioned extended in the X direction and the waist portion together with the shrinkage of the elastic element (64), a waist recoverer is formed.

As shown in Figures 1 and 4, the absorbent member (4) is an absorbent element comprising an absorbent polymer. the center (41) and a wrapper cover (42) surrounding this absorbent center (41).

In the diaper (1), the absorbent element (4) is perpendicular to the longitudinal direction (Y-direction). the liquid-retaining absorbent core (41) of the surrounding cover (42) which is a liquid-permeable hydrophilic layer. It is created by wrapping it in.

Regarding the absorbent core (41) as shown in Figure 1=. front part (A) in diaper (1) sides on both sides along the longitudinal direction (Y direction) on the side and along the longitudinal direction (Y direction) on the rear (B) side on both sides the edges run longitudinally from the edges on both sides of the crotch (C) (Y along the (X-direction) sideways outward sideways direction extends and its longitudinal direction (Y direction) from the central part to the anterior part (A) a part of it that is closer is narrowed inward when viewed as a whole. has been created. In addition, with respect to the absorbent core 41, the infant In the diaper (1), both the skin-facing surface and the non-skin-facing surface of the absorbent core (41) is also straight. Moreover, in the diaper (1), the absorbent core 41 is attached to the skin, as shown in Figure 2. a single layer of Iapa formed closest to the non-facing surface (410) has. In this way, at the absorbent center 41 of the diaper (1), the surface side not facing the skin the closest layer (410) is a single Iapa layer, and a layer other than this layer (410) the layer is a layer in which Iapa and absorbent polymer are mixed.

The absorbent core 41 of the diaper 1 described above, for example, the absorbent core 41 provided on the peripheral surface of a suction nozzle having a corresponding shape using a suction drum, first of all suction to store mash only by simply sucking the porridge from the mouth and then using the suction nozzle Iapa and absorbent polymer by suction to fill with the mixture and then stored in the suction mouth The mixture can be produced, for example, by feeding it to a vacuum conveyor. As described above In the absorbent core (41) produced, the single mash layer (410) and the other layer is created in an integrated and continuous manner.

As shown in Figures 1 and 2, the absorbent member (4) is in the wrapper covering the absorbent core 41. (42) covers a skin side of the skin-facing surface (421), a skin-side with the adhesive (5T) to a skin-facing surface (41T) of the absorbent core (41) (see Figure 2A) and a skin on the surface side not facing the skin in the wrapper (42) of the non-skin-side wrapping cover (422), a non-skin-side adhesive (5U) by securing the absorbent core (41) to a non-skin-facing surface (41U) (see Figure 2B). is created. In the diaper (1), a single layer of the wrapping cover 42, as shown in Figure 2, is used, and the parts on both sides of the wrapper cover (42) are folded to the top of the wrapper cover. The side edge portions (42) overlap each other on the backsheet (3) side of the absorbent core (41) it is allowed to ride on it. Thus, in the single layer of the wrapping cover 42, its absorbent partly located on the skin-facing surface (41T) side of the center (41) the wrapper becomes the cover (421) and its absorbent core (41) is the non-skin-facing surface (41U). a part of it placed on the side becomes the wrapping cover (422), which is not on the skin side.

Also, in the above-described diaper (1), the skin side of the wrapper (421 ) and the skin the non-side wrapping sheet 422 is formed from a single sheet of wrapping sheet 42; however, it is also possible for them to be formed from two different wrapping layers.
