Abstract
The present invention provides a disposable nursing pad having 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 2 and 3, 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 1 having an approximately conical shape. With the nursing pad 1, a connection portion 4 where pad pieces are joined forms a ridge which serves as the center line of the nursing pad 1. The nursing pad 1 can be folded along the ridge.
