The present invention to provide an absorbent structure adapted to prevent the liquid-absorbent materials from falling off the wrapping sheets. An aggregate of liquid-absorbent materials in an absorbent structure has an inner surface covered with a first wrapping sheet and an outer surface and lateral surfaces covered with a second wrapping sheet. The first wrapping sheet and the second wrapping sheet respectively have first extended portions lying outboard of the lateral surfaces and second extended portions wherein the first extended portions and the second extended portions are put flat and bonded together to form laminated regions. The laminated regions cover the lateral surfaces of the aggregate and part of the outer surface which, in turn, covers these lateral surfaces and the outer surface.
