A composite stretchable member which is stretchable in a longitudinal direction, comprising: two sheets (2a, 2b) which are opposed to each other; and a plurality of elastic elements each disposed between the sheets (2a, 2b) to extend along the longitudinal direction in such a manner as to be stretchable in the longitudinal direction, wherein: the sheets (2a, 2b) are bonded together in a plurality of bonding sections, each of the bonding sections being configured to continuously extend along a line intersecting the longitudinal direction and to intersect the plurality of elastic elements; and each of the elastic elements is bonded to the sheets (2a, 2b) at intersection points with the bonding sections, characterized in that the bonding sections are comprising: a plurality of first bonding sections extending parallel to each other along a first direction intersecting the longitudinal direction; and a plurality of second bonding sections extending parallel to each other along a second direction intersecting the longitudinal direction and the first direction, and each intersecting at least one of the first bonding sections. two sheets (2a, 2b) which are opposed to each other; and a plurality of elastic elements each disposed between the sheets (2a, 2b) to extend along the longitudinal direction in such a manner as to be stretchable in the longitudinal direction, wherein: the sheets (2a, 2b) are bonded together in a plurality of bonding sections, each of the bonding sections being configured to continuously extend along a line intersecting the longitudinal direction and to intersect the plurality of elastic elements; and each of the elastic elements is bonded to the sheets (2a, 2b) at intersection points with the bonding sections, characterized in that the bonding sections are comprising: a plurality of first bonding sections extending parallel to each other along a first direction intersecting the longitudinal direction; and a plurality of second bonding sections extending parallel to each other along a second direction intersecting the longitudinal direction and the first direction, and each intersecting at least one of the first bonding sections. the sheets (2a, 2b) are bonded together in a plurality of bonding sections, each of the bonding sections being configured to continuously extend along a line intersecting the longitudinal direction and to intersect the plurality of elastic elements; and each of the elastic elements is bonded to the sheets (2a, 2b) at intersection points with the bonding sections, characterized in that the bonding sections are comprising: a plurality of first bonding sections extending parallel to each other along a first direction intersecting the longitudinal direction; and a plurality of second bonding sections extending parallel to each other along a second direction intersecting the longitudinal direction and the first direction, and each intersecting at least one of the first bonding sections. a plurality of first bonding sections extending parallel to each other along a first direction intersecting the longitudinal direction; and a plurality of second bonding sections extending parallel to each other along a second direction intersecting the longitudinal direction and the first direction, and each intersecting at least one of the first bonding sections.
