A breast pad, comprising: a back sheet configured to prevent permeation of liquid; a liquid permeable top sheet configured to contact a user’s body; and an absorber that is disposed between the back sheet and the top sheet and configured to absorb and retain liquid that permeates the top sheet, wherein the top sheet and the back sheet are bonded to each other at an outer peripheral portion of the top sheet and the back sheet, cutout portions defined by cuts in the absorber are located at positions facing each other and at an outer peripheral portion of the absorber such that a cutout width of each of the cutout portions gradually narrows down inwardly towards a central area of the absorber, the top sheet and the back sheet are bonded to each other at the cutout portions, and the breast pad includes bonding portions located at and configured to bond inner facing surfaces of the top sheet together, the inner facing surfaces of the top sheet being superposed at each of the cutout portions when the breast pad is folded up along a folding line connecting the cutout portions so that the top sheet forms the inner surfaces, and an absorbing/dispersing layer with higher density than the absorber and located between the absorber and the top sheet, wherein the absorbing/dispersing layer is disposed on an inner side of each bonding portion.
