On the other hand, the middle section M (M2+M1+M2) of outer layer material 33 is formed without to be formed in the H2 of lower abdominal region Slot portion 38 non-gap zone 72 (hereinafter, in order to which the region and other non-gap zones are distinguished, also referred to as non-slot Region 72M).In addition, whole region of the side region outside portion S2 in the height width H of outer layer material 33 near side seal portion 25 is formed For non-gap zone 72 (hereinafter, in order to which the region and other non-gap zones are distinguished, also referred to as non-gap zone 72S)。

In this way, the gap zone 71A of outer layer material 33, across non-gap zone in the width direction of lower abdominal region H2 72M, and side region inside portion S1, S1 in left and right are formed with the queue that (slot) arranges at spaced intervals.In addition, with side seal portion When observing the veutro portion 21 and drosal part 23 of outer layer material 33 centered on 25, across non-gap zone 72S, gap zone 71A is formed For the queue arranged at spaced intervals in width direction.Each band portion 39 of gap zone 71 is in adjacent non-slot area as a result, Domain 72 links without being completely separate from each other.

The length of the width direction of non-gap zone 72M and 72S in the outer layer material 33 considers the following of gap zone 71 Effect and outer layer material 33 and internal layer material 31 bond strength and can suitably set.In order to effectively show gap zone 71 Effect, the length (length of m1=middle section (M2+M1+M2)) of the width direction of non-gap zone 72M is relative to slot area The ratio (m1/m2) of the length (length of the side region inside portion (S1+S1) of m2=or so) of the width direction of domain 71A is preferably 0.99 hereinafter, more preferably 0.94 or less.In order to ensure bond strength, lower limit is preferably 0.3 or more, more preferably 0.5 with On.In addition, the length (length of m3=side region outside portion (S2+S2)) of the width direction of non-gap zone 72S is relative to gap The ratio (m3/m2) for stitching the width direction length (m2) of region 71A is preferably 0.7 hereinafter, more preferably 0.5 or less.Its lower limit is excellent It is selected as 0.1 or more, more preferably 0.2 or more.In addition, the length of the length direction of non-gap zone 72M and 72S is not limited to figure Mode shown in 3 may be set to arbitrary length.Such as non-gap zone can also be formed in the whole region of height width H 72M。

Two sheet materials are engaged with the lamination area of internal layer material 31 and are integrally formed by such outer layer material 33, and in shorts type diaper 10 waistline direction, that is, width direction (X-direction) has retractility.

Specifically, in the gap zone 71 of outer layer material 33, each engaged with internal layer material 31 of multiple band portions 39 and have and stretch Contracting.In non-gap zone 72, outer layer material 33 engages to planar on height width H with internal layer material 31 and has retractility.It should Retractility is it is also preferred that being arranged elastomer 35 between internal layer material 31 and outer layer material 33 and obtaining.In this case, elastomer 35 is being stretched It is clamped under long status between internal layer material 31 and outer layer material 33, thus there is retractility.Alternatively, detailed narration as follows, It is preferred that internal layer material 31 and the two in outer layer material 33 or any one be made of the material with retractility.

In gap zone 71, the gap in slot portion 38 is caused because of the contraction of the width direction of the exterior body with retractility Expand, becomes the ventilation mouth of veutro portion 21 and drosal part 23.In addition, the body of wearer after exterior body 11 is because wearing diaper 10 Movement of body etc. and when elongation-contraction, ventilation mouth is opened and closed with cooperating the movement, promotes the moisture discharge in diaper, is further mentioned Highly-breathable.
