Description

また、図１に示すように、本実施形態に係る吸収体３０は、ウイング領域ＣＡの前後方向Ｌ中心における吸収体３０の幅方向Ｗの長さＷ１は、前領域ＦＡと後領域ＢＡとの内、少なくとも前領域ＦＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ａよりも大きい。本実施形態において、前領域ＦＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ａと、後領域ＢＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ｂとは、略同じである。従って、本実施形態では、図１に示すように、吸収体３０の幅方向Ｗの長さＷ１は、前領域ＦＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ａと、後領域ＢＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ｂよりも大きい。 Further, as shown in FIG. 1, the absorber 30 according to the present embodiment has a length W1 in the width direction W of the absorber 30 at the center in the front-rear direction L of the wing area CA. Among these, at least the maximum length W2A in the width direction W of the absorber 30 in the front region FA is larger. In the present embodiment, the maximum length W 2 A in the width direction W of the absorber 30 in the front region FA and the maximum length W 2 B in the width direction W of the absorber 30 in the rear region BA are substantially the same. . Therefore, in the present embodiment, as shown in FIG. 1, the length W1 of the absorber 30 in the width direction W is equal to the maximum length W2A of the absorber 30 in the width direction W in the front region FA and the absorption in the rear region BA. maximum length in the width direction W of the body 30 W2 greater than B.

なお、本実施形態では、前領域ＦＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ａに着目して説明する。但し、変形例において、前領域ＦＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ａと、後領域ＢＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ｂとが異なっていてもよい。また、この場合、吸収体３０の幅方向Ｗの長さＷ１は、少なくとも前領域ＦＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ａよりも大きく構成される。 In the present embodiment, description will be given focusing on the maximum length W2A in the width direction W of the absorber 30 in the front region FA. However, in the modification, even if the maximum length W 2 A in the width direction W of the absorber 30 in the front region FA and the maximum length W 2 B in the width direction W of the absorber 30 in the rear region BA are different. Good. In this case, the length W1 of the absorber 30 in the width direction W is configured to be at least larger than the maximum length W2A of the absorber 30 in the width direction W in the front region FA.

なお、本実施形態では、ウイング領域ＣＡの前後方向Ｌ外側の端部から後領域ＢＡの内部にわたって、吸収体３０の幅方向Ｗ外側の両端部は、前後方向Ｌに平行に延びる。従って、本実施形態では、ウイング領域ＣＡの前後方向Ｌ外側の端部における吸収体３０の幅方向Ｗの長さＷ３と、後領域ＢＡにおける吸収体３０の幅方向Ｗの最大長さＷ２Ｂとは、同じである。 In the present embodiment, both end portions on the outer side in the width direction W of the absorber 30 extend in parallel with the front-rear direction L from the end portion on the outer side in the front-rear direction L of the wing region CA to the inside of the rear region BA. Accordingly, in the present embodiment, the length W3 in the width direction W of the absorber 30 in the longitudinal direction L outer end of the wing area CA, and the maximum length W2 B in the width direction W of the absorber 30 in the rear region BA Are the same.

（作用及び効果）
本実施形態に係る吸収性物品１では、ウイング領域ＣＡの前後方向Ｌ中心における吸収体３０の長さＷ１が、前領域ＦＡ及び後領域ＢＡにおける吸収体３０の幅方向Ｗの長さＷ２Ａ，Ｗ２Ｂよりも大きい。よって、かかる吸収性物品によれば、吸収体のウイング領域ＣＡの前後方向Ｌ中心における吸収体の幅方向の長さが、前領域ＦＡおよび後領域ＢＡにおける吸収体の幅方向の最大長さＷ２Ａ及びＷ２Ｂよりも小さい場合に比べて、すなわち、吸収体のウイング領域の前後方向中心において吸収体の幅方向内側に凹むように形成されている吸収性物品に比べて、吸収性物品１の幅方向Ｗ内側への強度が高められるため、ウイング領域ＣＡの前後方向Ｌ中心に発生するヨレを抑制することができる。 (Function and effect)
In the absorbent article 1 according to the present embodiment, the length W1 of the absorber 30 at the center in the front-rear direction L of the wing area CA is the length W2 A of the absorber 30 in the width direction W in the front area FA and the rear area BA . Greater than W2B . Therefore, according to such an absorbent article, the length in the width direction of the absorber at the front-rear direction L center of the wing area CA of the absorber is the maximum length W in the width direction of the absorber in the front area FA and the rear area BA. Compared to the case where it is smaller than 2 A and W 2 B, that is, compared to the absorbent article formed so as to be recessed inward in the width direction of the absorber at the center in the front-rear direction of the wing region of the absorber. Since the strength inward in the width direction W of 1 is increased, the twist generated at the center in the front-rear direction L of the wing area CA can be suppressed.
