Under the state of mother's bosom, mother is supporting wearer's waistline, if still wish is moved wearerMove bed first-class, mother's supporting disappears. But the disposable diaper of present embodiment is configured to logicalThe body pressure of crossing wearer puts on as the absorber of support unit absorber is manifested dressThe supporting of person's health. Therefore, because wearer lies on a bed etc., therefore support unit supporting wearerHealth. Even in the case of mother's etc. supporting disappears, also can realize in analog mother's bosomState. The applicant has carried out various checkings, and result manifests, and feels in analog by mother by infantThe state of bosom, thus be easy to make infant's stable sleep to continue. Therefore, simulate by infantThe state of being held in the arms by mother is felt on ground, thereby is easy to make infant's stable sleep to continue.

Because body pressure puts on absorber 30, therefore absorber compression, extensive at this absorberUnder the effect of multiple power, absorber supporting wearer's health. Due to the absorber passing through as support unitThe distortion of self manifests the supporting of the health to wearer, therefore with have for detection of having applied healthThe structure of the detection part of the situation of pressure etc. is compared, and can utilize simple structure to realize wearerThe supporting of health.

In addition, the applicant is conscientiously research repeatedly, and result manifests, and infant shrinks like that in health front sideAnteflexion posture (make leg from root bending and make the posture of leg near veutro) be easy to feel at ease sleep.For example, under the state of mother bosom, mother is supporting wearer's leg, and wearer's leg is near veutro,First-class but if wearer is moved to bed by wish, mother's supporting disappears.

The disposable diaper of present embodiment is by utilizing leg support hemad above to push away wearer's leg, fromAnd be easy to the posture that remains anteflexion, be easy to maintain the feel at ease state of sleep of infant.

According to the disposable diaper of formation like this, no matter be the state that mother holds in the arms, still leave mother'sState, can both realize bosom sense, is easy to suppress by the sense of insecurity that leaves the infant that mother causes.

Low as the shrinkage stress of the 2nd rear region RR2 of buttocks abutting part of buttocks that is connected to wearerIn the shrinkage stress of the 1st rear region RR1 that disposes rear leg elastic member. If taking health front side receivesSuch anteflexion posture that contracts, wearer's skin is flexible, if near the skin particularly buttocks is takedSuch anteflexion posture is shunk in health front side, extends 30% left and right with respect to the state of body line up.Now, because the shrinkage stress of buttocks abutting part is lower, therefore can suitably follow the flexible of skin.Therefore, wearer can easily take health front side to shrink such anteflexion posture, once and work asWhile having taked anteflexion posture, be easy to maintain this posture.

The shrinkage stress of the 2nd forefoot area RF2 of belly abutting part that forms the belly that is connected to wearer is lowIn the expansion and contraction of shrinkage stress of the 1st forefoot area RF1 that disposes front leg portions elastic component. For as wearingThe person's of wearing infant, the portion of heaving of wearer's abdomen becomes according to the situation of diet, excretion conventionallyChange. Owing to being connected to, the shrinkage stress of the 2nd forefoot area RF2 of belly is lower, therefore can not tie tight and wearUnder the prerequisite of the person's of wearing belly, cosily cover belly.

In addition, because leg elastic member is enclosed with the leg of the wearer's that furthers towards veutro rear waist portion sideMode is shunk, and is therefore easy to the nearly wearer's of layback leg forward. The shape of being held in the arms by mother infantUnder state, infant becomes health front side and shrinks such anteflexion posture. Therefore, infant is by takingSuch anteflexion posture is shunk in health front side, thereby infant feels the shape of being held in the arms by mother in analogState, infant is easy to obtain the sense of security. Infant can easily take health front side shrink such beforePosture in the wrong, is easy to sleep securely.

Because the expansion and contraction of the 1st forefoot area that disposes front leg portions elastic component is higher than disposing rear shank bulletThe 1st rear region expansion and contraction of property member, therefore the leg of front waist portion encloses peristome and encloses than the leg of rear waist portionPeristome shrinks to a greater degree. Therefore, be easy to the nearly wearer's of layback leg forward.
