PROBLEM TO BE SOLVED: To provide a laminated nonwoven fabric that employs a core-sheath type composite filament made of a specific material and an ultra fine fiber made of a specific material, which are integrated without forming an ultrafine fiber nonwoven fabric layer into a film, and can prevent the lowering of air permeability and the dispersion of a powder to the outside.SOLUTION: The laminated nonwoven fabric comprises: a surface layer and a rear surface layer, which are formed of an accumulation body of a core-sheath type composite filament having a sheath component made of high-density polyethylene and a core component made of polyester having a higher melting point than the sheath component and an intermediate layer which is formed of an accumulation body of an ultra fine fiber made of polypropylene or polybutylene terephthalate, which has a higher melting point than a melting point of the sheath component. A plurality of sheath components in the surface layer melts, separates from the core component, enters a space between the ultra fine fibers and is solidified. The sheath component in the rear surface layer is softened or melts without being separated from the core component and is solidified, and thereby the rear surface layer and the intermediate layer are laminated.
