a waist band including a belt-shaped body with hook materials and engagement portions attached to both end portions thereof, first and second ventral-side engagement portions across which the engagement members at the ventral-side portion of the absorbent pad are engaged, and first and second back-side engagement portions across which the engagement members at the back-side portion of the absorbent pad are engaged; and hook materials capable of engaging with the engagement members of the absorbent pad are attached to internal surfaces of the first and second ventral-side engagement portions and the first and second back-side engagement portions. ## Claims ### Claim 1 An absorbent article having an absorbent pad and a waist band across which the absorbent pad is attached, wherein the absorbent pad includes: a liquid pervious top sheet; a liquid impervious back sheet; an absorbent body extending longitudinally between the liquid pervious top sheet and the liquid impervious back sheet at least from a crotch portion to a back-side portion; and an outer sheet on an external surface of the liquid impervious back sheet, and wherein engagement members with indications of attachment positions are arranged at both corners of a ventral-side portion and a back-side portion on an external surface of the outer sheet, the waist band includes: a belt-shaped body having a belt-shaped nonwoven fabric and resilient members arranged in a stretched state along a periphery of the nonwoven fabric; a hook material of a mechanical fastener that is attached to one peripheral end portion of the belt-shaped body, and an engagement portion that is attached to the other peripheral end of the belt-shaped body and is capable of engaging with the hook material; a first ventral-side engagement portion across which the engagement members at the ventral-side portion of the absorbent pad are engaged, and a first back-side engagement portion across which the engagement members at the back-side portion of the absorbent pad are engaged, at a portion of the belt-shaped body opposed to the right iliac bone of a wearer; a second ventral-side engagement portion across which the engagement members at the ventral-side portion of the absorbent pad are engaged, and a second back-side engagement portion across which the engagement members at the back-side portion of the absorbent pad are engaged, at a portion of the belt-shaped body opposed to the left iliac bone of a wearer, and wherein hook materials of mechanical fasteners capable of engaging with the engagement members of the absorbent pad are attached to internal surfaces of the first and second ventral-side engagement portions and the first and second back-side engagement portions, and the first and second ventral-side engagement portions and the first and second back-side engagement portions are inclined with respect to the longitudinal direction of the belt-shaped body, and extend beyond a lower waist portion opening edge of the belt-shaped body. ### Claim 2 (depends on 1) The absorbent pad according to claim 1, wherein leg-around resilient members are arranged at side flap portions of the absorbent pad, and the leg-around resilient members extend longitudinally from the crotch portion to positions opposed to the engagement members at the ventral-side portion and the back-side portion of the outer sheet. ### Claim 3 (depends on 2) The absorbent article according to claim 2, wherein temporary fastening members are arranged at end flap portions of the absorbent pad. ### Claim 4 (depends on 1) The absorbent article according to claim 1, wherein fixed portions of the first and second ventral-side engagement portions with the belt-shaped body are formed at a position opposed to the iliac bone of a wearer, and a shape of the fixed portions is approximate to a substantially triangular shape of the iliac bone. ### Claim 5 (depends on 1) The absorbent article according to claim 1, wherein an end of the first ventral-side engagement portion and an end of the second back-side engagement portion are fixed with a clockwise inclination of 30 to 60 degrees with respect to the periphery of the belt-shaped body, and an end of the second ventral-side engagement portion and an end of the first back-side engagement portion are fixed with a counterclockwise inclination of 30 to 60 degrees with respect to the periphery of the belt-shaped body. ### Claim 6 (depends on 1) The absorbent article according claim 1, wherein when being stretched by 150%, a stretching stress of the resilient members arranged at the waist portion of the belt-shaped body is 10 to 35 g, and a stretching stress of the resilient members arranged at the lower waist portion of the belt-shaped body is 4 to 15 g. ### Claim 7 (depends on 1) The absorbent article according to claim 1, wherein recognizable marks are provided on an external surface of an end portion and an external surface of a peripherally central portion of the belt-shaped body, such that the ventral-side central portion and the back-side central portion have the marks when the belt-shaped body is shaped in a circle, and a longitudinally extending recognizable mark is provided at the laterally central portion of the outer sheet of the absorbent pad. ### Claim 8 (depends on 1) The absorbent article according to claim 1, wherein first cut-off portions are formed from end pieces of the lower waist portion at both end portions of the belt-shaped body, a second cut-off portion is formed from an end piece of the lower waist portion at an peripherally central portion of the belt-shaped body, and when the belt-shaped body is shaped in a circle, the belt-shaped body has a ventral-side cut-off portion including the pair of first cut-off portions and a ventral-side cut-off portion including the second cut-off portion. ### Claim 9 (depends on 1) The absorbent article according to claim 1, wherein a first skin protection portion is provided on the internal surface of the belt-shaped body opposed to the right iliac bone of a wearer, and a second skin protection portion is provided on the internal surface of the belt-shaped body opposed to the left iliac bone of a wearer.
