Here, since no body fluid such as menstrual blood adheres to the tape member 60, it is possible to prevent a decrease in the bonding strength between the tape member 60 and the main adhesive unit 70 or a reduction in the bonding strength of the fastening means of the tape member. it can. Furthermore, during use of the absorbent article 10, the tape member 60 is provided on the non-skin facing surface side of the back sheet 22 and does not extend outside the outer edge 20E of the main body 20, so the tape member 60 is worn Does not hit the person's skin directly. Therefore, discomfort and discomfort during use can be reduced.

  In another embodiment, the tape member 60 may extend outward beyond the outer edge 20E of the main body 20 in a non-extended state (natural state). The tape member 60 may be visible when viewed from the skin facing surface side.

  In the configuration in which the tape member 60 is fixed to the main body portion 20 by the main body adhesive portion 70, the length of the cross direction C orthogonal to the extension direction D of the main body adhesive portion 70 is the length of the cross direction C of the extension portion 64. It may be longer than Specifically, as shown in FIG. 2, the length W 2 in the width direction of the main adhesive portion 70 may be longer than the length W 1 in the width direction W of the extension portion 64. Depending on the user, when extending the extension portion 64, the extension portion 64 may be pulled obliquely with respect to the extension direction D without being pulled parallel to the extension direction D. Since the length W2 in the cross direction C of the main body adhesive part 70 is longer than the length W1 in the cross direction C of the extension part 64, the extension part 64 can be stretched even if it is pulled diagonally with respect to the extension direction D. It becomes easy to fasten to the main body adhesive part 70.

  The recommended elongation limit is not an elongation limit at which the tape physically breaks but may be an elongation limit recommended by the designer. The recommended extension limit may be an upper limit that can be extended without breaking the tape member, or may be an upper limit that can extend without changing the physical properties of the tape member. The recommended elongation limit can be designed, for example, up to 70 to 80% with respect to the breaking magnification (hereinafter referred to as breaking elongation). 70-80% is a safety factor and can be set suitably. The breaking extension ratio can be calculated by the length of the breaking state / the length of the natural state.

  The mark 80 may indicate the extendable length DA as a recommended extension limit. The extendable length DA is a state in which the tape member 60 extends in the extension direction D at the recommended extension limit and the extension direction D of the extension part 64 in the maximum extension state (hereinafter referred to as the maximum extension length D2); That is, it is a difference from the length in the extension direction D of the extension portion 64 in the natural state (hereinafter, referred to as a natural length D1). That is, DA = D2-D1.

  The maximum extension length D2 can be calculated by the length in the extension direction D of the extension part 64 × breaking extension ratio × safety factor. The natural length is the length in the extension direction D of the extension portion 64 in the natural state. FIG. 4 (A) shows the tape member 60 in the natural state, and FIG. 4 (B) shows the tape member 60 in the maximally stretched state. Here, in the natural state, in the case of the absorbent article contained in the package, the absorbent article is removed from the package, and it is kept for 24 hours in an atmosphere of 20 ° C. ± 2 ° C. and relative humidity 60% ± 5% RH. It is in the state of leaving it.

Therefore, it is possible to prevent the user from excessively stretching the tape member 60 and breaking the tape member 60 unintentionally.

  Further, when setting the extendable length DA, it may be assumed that a part of the extension part 64 can be extended without assuming that the entire extension part 64 can extend. . Specifically, when the user extends the tape member 60, the user holds and extends a part of the extension portion 64. Therefore, the extendable length DA may be set on the assumption that the portion excluding the gripped portion has an extendable length without assuming that the entire extension portion 64 extends. Specifically, when the length of the tape member 60 in the extension direction D is 45 mm and the length of the fixing portion 62 in the extension direction D is 10 mm, the length of the extension portion is not 35 mm, and the hand portion is 10 mm. Assuming that 25 mm is set as the length of the extension, the recommended extension limit may be set.
