Abstract

An absorbent article has a wrapping sheet wrapping an absorbent body including an intermediate part located on one side of front face side and back face side of the body and both side parts folded back to the other side of the body from the intermediate part. Distal ends of the both side parts are overlapped on the other side of the body to form a connecting portion. A whole part of an internal surface of the wrapping sheet faces the body and is bonded to an external surface of the body through hot melt adhesives. A usage amount of the hot melt adhesives bonds the wrapping sheet and the body together and is larger at least in a region of both end portions in a width direction on the other side of the body than on the one side of the body.
