Engaged preferably by the hot-melt adhesive being discontinuously coated with as point-like, wire or helical form between 91.Additionally,
Can also be engaged by heat-sealing etc. between hook tabs 92 and substrate sheets 91.
Substrate sheets 91 are made up of 1 non-woven fabrics or more than two multiple non-woven fabrics for overlapping are constituted.As substrate sheets
91, the non-woven fabrics manufactured using the manufacture method such as spunbond (SB) or spunbond-melt blown-spunbond (SMS) can be used.Constitute base
The weight per unit area summation of weight per unit area (in the case of multiple be) of the non-woven fabrics of material piece 91 is 30g/m2~
120g/m2, preferably 40g/m2~90g/m2。
Additionally, in the case where the layered product being laminated by multiple non-woven fabrics constitutes substrate sheets 91, unit can be used
Area weight 10g/m2~80g/m2Non-woven fabrics, it is further preferred that 15g/m can be used2~75g/m2Non-woven fabrics.True
Protect magic tape intensity (fracture strength) and formed softness band in the case of, by multiple non-woven fabrics overlap and each other
Composition surface at have a case that junction surface and disengaged portion than a non-woven fabrics can more constitute softness magic tape.
Substrate sheets 91 are configured between flank 70 and outer load 60, and with the 1st region R1 of the configuration that overlapped with flank
With the 2nd region R2 for extending to the position leaned on the outside of product width direction than flank.Additionally, substrate sheets are at least connected with flank
The structure that can, or do not link with outer load 60.
Substrate sheets 91 have：Junction surface 93, it is engaged in flank；And top ends 96, it is extended to than hook tabs 92 by producing
Position on the outside of product width.The junction surface 93 of the substrate sheets 91 of present embodiment is to be engaged in flank 70 or outer load
Region.Junction surface 93 is in the 1st region R1.Additionally, part of the junction surface 93 located at the 1st region R1, but it is also possible to located at whole
Individual 1st region R1.Top ends 96 are extended to than hook tabs 92 by the position on the outside of product width direction, and including the width of magic tape 90
Outboard end on degree direction.
Length L11 on the product width direction W of the top ends 96 of substrate sheets 91 is 5mm~12mm.Top ends 96 are not
Hook tabs 92 is set and the part of target portion is not secured in the state of magic tape 90 is fixed on target portion.Top ends 96 are to supply
The part that wearer holds when tearing open and closing magic tape 90.It is therefore desirable to, there is top ends 96 confession wearer to be easy to what is held
Size.Using the top ends 96 of such size, wearer can be held with finger, and can successfully carry out magic tape 90
Tear closing operation open.In addition, wearer can reliably hold top ends 96, carried out thus, it is possible to the installation site to magic tape 90
Fine setting, and desired position can be installed on.Thereby, it is possible to lift operability during wearing.
Outboard end in outboard end in the product length direction at junction surface 93 and the product length direction of hook tabs it
Between in product length direction apart from L12 be 2mm~12mm.Hook tabs is affixed to the part of target portion, by by hook tabs
Area sets larger, it is possible to increase adhesion.However, in conventional magic tape 90, if expanding the area of hook tabs, for connecing
The area for closing the junction surface 93 of magic tape 90 becomes big, it is possible to cause due to the sense of discomfort that rigidity region higher increases and causes
Become strong.
However, by by the product length direction of the outboard end in the product length direction at junction surface 93 and hook tabs
The distance between outboard end L12 is set as 2mm~12mm, is obtained in that the adhesion brought by hook tabs, and suppress by engaging
Sense of discomfort when wearing that portion 93 causes.
In addition, products of length L13 of the boundary between hook tabs and top ends 96 in product length direction for substrate sheets 91
Between medial end on product length direction and the medial end in the product length direction of hook tabs in product length direction
Apart from more than 2 times of L14.The leg of the calf circumference that formation surrounds wearer is opened in the state of magic tape 90 is fixed on target portion 95
Oral area 35.In the state of leg opening part 35 is formd, magic tape 90 is located at the vicinity of leg opening part 35.Thus, wear
During person's movable leg, magic tape 90 encounters the leg of wearer sometimes.Particularly, the medial extremity in the product length direction of substrate sheets 91
Easily encounter the leg of wearer in portion.
In addition, the medial end in the product length direction of substrate sheets 91 is adhesion not pair and target portion between making
The region of contribution.Accordingly, it is desirable to be the medial end in the product length direction of substrate sheets 91 and the product length direction of hook tabs
On medial end between it is shorter apart from L14 in product length direction, it is shorter apart from L14, then can more not make not pair and mesh
The region that adhesion between mark portion contributes narrows, so that magic tape is difficult to encounter the leg of wearer.
And, magic tape 90 be in gone on the outside of lateral product width direction from product width direction and in product width direction
Length shorten top point shape.Therefore, the product length direction of the boundary hook tabs between hook tabs and top ends 96
On length it is most short.Base is set to by the length L13 by the boundary between the hook tabs and top ends 96 in product length direction
It is long in product between medial end in the product length direction of material piece 91 and the medial end in the product length direction of hook tabs
More than 2 times apart from L14 on degree direction, magic tape can be suppressed and meet wearer, and ensure adhesion.
In addition, hook tabs is extended to than intermediate point C1 by the position on the outside of product length direction, the middle C1 is the product of hook tabs
The product width side of outboard end in the product length direction at the medial end on product width and top ends 96
The intermediate point between the outboard end in the product length direction at upward medial end.Hook tabs is in from product width side
Inwardly lateral product width direction outside is gone and the shape of top point that the length in product width direction shortens.Therefore, in hook
Medial end in the product width direction of piece and the outboard end in the product width direction of hook tabs, hook what material was brought
Adhesion is different.Therefore, the adhesion of whole hook tabs produces uneven.
In addition, in the state of leg opening part 35 is formd, magic tape 90 is located at the vicinity of leg opening part 35, is wearing
During the person's of wearing movable leg, effect sometimes has the power for taking magic tape 90 off from target portion.Now, the power of magic tape 90 is taken off from target portion
Act on since the side of leg opening part 35.If the product of the adhesion of the medial end in the product width direction of hook tabs and hook tabs
Difference between the adhesion of the outboard end on width is larger, then occasionally result in magic tape 90 to stronger with adhesion
Part be starting point rotated direction movement, and front waist region and rear waist region position, direction skew.
However, because hook tabs is extended to than intermediate point by the position on the outside of product length direction, the intermediate point is hook tabs
The product width of outboard end in the product length direction at the medial end in product width direction and top ends 96
The intermediate point between the outboard end in the product length direction at medial end on direction, therefore wider than hook tabs
Degree direction center by the adhesion in the whole region on the outside of width can be close in the product width direction of hook tabs in
The adhesion of side end, and the inequality of adhesion can be suppressed.
Hook tabs is extended to than intermediate point C2 by the position on the outside of product length direction, and intermediate point C2 is the 1st region and the 2nd
Outboard end in the product length direction of the boundary between region and the outboard end in the product width direction in the 2nd region
The intermediate point between outboard end in the product length direction at place.Length in the product length direction of magic tape 90 is to product
Width outside go and gradually shorten, if but for example, as magic tape 90 root width inner side become too short,
It is likely to result in ensuring the area of top ends 96, or the adhesion that the hook tabs of the side of top ends 96 cannot be ensured.However, by
Extended to than intermediate point C2 by the position on the outside of product length direction in hook tabs, intermediate point C2 be the 1st region and the 2nd region it
Between boundary product length direction on outboard end and the 2nd region product width direction on outboard end at product
The intermediate point between outboard end on product length direction, the area therefore, it is possible to make the side of top ends 96 of magic tape 90 becomes big.
The profile in the 2nd region of substrate sheets is curve shape.2nd region of substrate sheets is the area extended out from flank
Domain, and be the part that hand is touched in wearing.The profile in the 2nd region of substrate sheets is curve shape, thereby, it is possible to suppress opponent
Stimulation, and lifting operation.In addition, in the case where leg, hand are unexpectedly encountered in the end of substrate sheets, can be by leg etc.
Line pressure caused by stimulation and thread gluing strap end portion remains relatively low.Additionally, at least one of the profile in the 2nd region of substrate sheets
It is divided into curve shape, a part for the profile in the 2nd region of substrate sheets can also be rectilinear form.
It is desirable that, the distance between hook tabs 92 and junction surface 93 L15 are 2mm~12mm.Because junction surface 93 is engaged in
Flank, and hook tabs 92 is fixed on target portion 95 in the state of disposable diaper has been dressed, thus hook tabs 92 and junction surface 93 it
Between region be that any region and yielding region have been not secured in the state of disposable diaper has been dressed.If hook tabs 92 with
The distance between junction surface 93 is long, then easily deformable when effect has external force in wearer's movable leg etc., so as to be difficult to maintain
The bonding state of magic tape 90.On the other hand, if hook tabs 92 is too short with the distance between junction surface 93, do not lived in wearer
The region deformed during dynamic leg etc., it is possible to hinder the free motion of wearer.Between hook tabs 92 and junction surface 93 away from
From being 2mm~12mm, thereby, it is possible to ensure the bonding state for freely moving and maintaining magic tape 90.
It is desirable that, being formed with as protruding outside towards product length direction in the product length direction end of substrate sheets
