A patent was issued for an interlabial pad having a substantially vertically elongated shape and comprising a top sheet, a back surface sheet and an absorbent body disposed between the top sheet and the back surface sheet, the interlabial pad being folded in two along a central longitudinal axis such that the back surface sheet faces itself and configured such that a wearer can wear the pad so that a portion of the pad near the central longitudinal axis of the pad is aligned in use with the vestibular floor of the wearer and at least a part of the pad resides within a labia minora pudenda between labia of the wearer, wherein: the interlabial pad includes a first portion configured to make contact with the wearer in use near the vestibular floor and a second portion configured to make contact with the wearer in use near anterior ends of the labia minora pudenda, the interlabial pad is folded such that at least a portion of the back surface sheet corresponding to the second portion makes contact with the wearer during use, the absorbent body is formed as a single layer, and the absorbent body as positioned at the first portion is thicker than another part of the absorbent body in the second portion in a state in which the interlabial pad is folded in two and also in a state in which the interlabial pad is not folded in two such that a compressive repulsive force generated by compressing the first portion is greater than a compressive repulsive force generated by compressing the second portion.
