Absorbent article

A method for manufacturing an absorbent article comprising a liquid retentive absorbent layer, a liquid impermeable leak preventive layer and a leak preventive wall disposed along opposite side edges of said absorbent layer, said leak preventive wall comprising a basal wall portion and a planar elastic expansible/contractible portion connected to an upper end portion of said basal wall portion and being raised in an excretion portion facing section which is placed opposite a wearer's liquid excretion portion, when in wear, and a rear section which is placed more on the back side than said excretion portion facing section, when in wear, and a distance from an upper end portion of said basal wall portion to said leak preventive layer in said rear section is shorter than a comparable distance in said excretion portion facing section,

• said method for manufacturing an absorbent article comprising a step of manufacturing a main body which comprises said absorbent layer or said absorbent layer and said leak preventive layer, a step of manufacturing an elastic expansible/contractible member which comprises a basal wall portion forming sheet portion having a constant width in the longitudinal direction and said elastic expansible/contractible portion connected to widthwise one end portion of said basal wall portion forming sheet portion, and a step of fixing said basal wall portion forming sheet portion of said elastic expansible/contractible member to opposite side portions of said main body so that a fixed position in the widthwise direction of said basal wall portion forming sheet portion in said excretion portion facing section and a fixed position in the widthwise direction of said basal wall portion forming sheet portion in said rear section are differentiated.
