A hook-and-loop fastener female member, comprising: an engaging layer engageable with a hook-and-loop fastener male member; and a physical property layer configured to hold the engaging layer, wherein the engaging layer includes a non-woven fabric of fiber, wherein a material for the physical property layer is a non-woven fabric of fiber, wherein the hook-and-loop fastener female member has an embossed pattern, wherein the thickness of the welded portion formed by the embossed pattern is 100 μ m or less, and wherein the hook-and-loop fastener female member has a flexibility index A, which is expressed by Equation, of 0.004 g -2 or more: A = 1 / P 1 × P 2 where: P1 represents a maximum compressive load when a ring body, which is obtained by cutting the hook-and-loop fastener female member into a size of 25 mm in an MD direction by 50 mm in a CD direction, forming the cut hook-and-loop fastener female member into a ring shape with its physical property layer surface being a roll inner side and its CD being a circumference, and connecting a front end portion and a rear end portion of the hook-and-loop fastener female member to each other at two places through use of a stapler in such a manner that the end portions do not overlap each other so as to have a ring shape having a roll diameter of 20 mm, is deformed through application of a compressive load to the ring body from its axial direction at a speed of 50 mm/minute up to 14 mm; and P2 represents a maximum compressive load when the ring body, which is obtained by cutting the hook-and-loop fastener female member into a size of 25 mm in an MD direction by 50 mm in a CD direction, forming the cut hook-and-loop fastener female member into a ring shape with its physical property layer surface being a roll inner side and its CD being a circumference, and connecting the front end portion and the rear end portion of the hook-and-loop fastener female member to each other at two places through use of a stapler in such a manner that the end portions do not overlap each other so as to have a ring shape having a roll diameter of 20 mm, is deformed through application of a compressive load to the ring body from its width direction by allowing a plastic plate to fall freely at a height of 35 mm down to 5 mm. an engaging layer engageable with a hook-and-loop fastener male member; and a physical property layer configured to hold the engaging layer, wherein the engaging layer includes a non-woven fabric of fiber, wherein a material for the physical property layer is a non-woven fabric of fiber, wherein the hook-and-loop fastener female member has an embossed pattern, wherein the thickness of the welded portion formed by the embossed pattern is 100 μ m or less, and wherein the hook-and-loop fastener female member has a flexibility index A, which is expressed by Equation, of 0.004 g -2 or more: A = 1 / P 1 × P 2 P1 represents a maximum compressive load when a ring body, which is obtained by cutting the hook-and-loop fastener female member into a size of 25 mm in an MD direction by 50 mm in a CD direction, forming the cut hook-and-loop fastener female member into a ring shape with its physical property layer surface being a roll inner side and its CD being a circumference, and connecting a front end portion and a rear end portion of the hook-and-loop fastener female member to each other at two places through use of a stapler in such a manner that the end portions do not overlap each other so as to have a ring shape having a roll diameter of 20 mm, is deformed through application of a compressive load to the ring body from its axial direction at a speed of 50 mm/minute up to 14 mm; and P2 represents a maximum compressive load when the ring body, which is obtained by cutting the hook-and-loop fastener female member into a size of 25 mm in an MD direction by 50 mm in a CD direction, forming the cut hook-and-loop fastener female member into a ring shape with its physical property layer surface being a roll inner side and its CD being a circumference, and connecting the front end portion and the rear end portion of the hook-and-loop fastener female member to each other at two places through use of a stapler in such a manner that the end portions do not overlap each other so as to have a ring shape having a roll diameter of 20 mm, is deformed through application of a compressive load to the ring body from its width direction by allowing a plastic plate to fall freely at a height of 35 mm down to 5 mm.
