Abstract
A disposable nursing pad has a layered structure of a liquid-permeable sheet, an absorbent body, and a liquid-impermeable sheet. The liquid-permeable sheet and the liquid-impermeable sheet are adhered to each other. This prevents the liquid-permeable sheet from becoming detached from the absorbent body, and provides a nursing pad having an improved capacity to maintain its three-dimensional shape. A pair of pad pieces, each of which has a layered structure of a liquid permeable sheet piece, an absorber, and a liquid-impermeable sheet piece, is joined so as to form a nursing pad having an approximately conical shape. With the nursing pad, a connection portion where pad pieces are joined forms a ridge which serves as the center line of the nursing pad. The nursing pad can be folded along the ridge.
