First fin 41 is swimmingly separated into two.In addition, since fin is difficult to be torn along width direction, so, by fin
When being installed on underwear, or in the wearing of absorbent commodity, fin is difficult to be torn in the direction of the width, can inhibit
Fin is inadvertently detached when installation or in wearer.In addition, constitute fin material can along tearing strength in the front-back direction
It is low along the tearing strength of width direction with the material than being constituted fin.By constitute the first fin 41 material readily along
Front-rear direction is torn, and the tearing position of the first fin 41 extends readily along front-rear direction, can prevent in the direction of the width
It is torn and absorber is made to expose.First fin 41 becomes easy is being separated into two along tearing position in the front-back direction.
In addition, the tearing strength of fin is intensity in the state of with tearing induction portion, the material of fin is constituted
Tearing strength is intensity in the state of being not provided with tearing induction portion.Constitute the strong of the material of the fin in present embodiment
Degree is by the intensity in the state of side piece 12 and the overlapping of non-skin dough sheet.
In addition, the tensile strength along width direction of fin can be than fin along tearing strength in the front-back direction
Height, so that fin is unlikely to unintentionally be torn via tearing induction portion when mounted.Since fin is along width direction
Tensile strength is higher along tearing strength in the front-back direction than fin, so, it is destroyed relative to the power of width direction in fin
Before, fin is destroyed readily along front-rear direction.Thus, when unloading absorbent commodity, power can be effectively applied to tear
Induction portion is split, can easily be detached fin.In addition, the tensile strength along width direction for constituting the material of fin can be with
It is higher along tensile strength in the front-back direction than the material of composition fin.Preferably, the tensile strength in the width direction of fin
It can also be in 2N/25mm or more.It is difficult to rupture according to the structure, when fin is stretched in the direction of the width, when mounted, fin
It is not easy unexpectedly to be torn via tearing induction portion.
