The present invention relates to a composite structure for noise insulation applicable to broadband frequencies and multiple composite sheets including the same, which can have great noise insulation effects. More specifically, the composite structure for noise insulation comprises: a first sheet layer in which hexagonal first pattern regions are formed in a lattice structure; an elastic film layer which is laminated on the first sheet layer and includes a polymer; and a second sheet layer which is laminated on the elastic film layer and in which hexagonal second pattern regions are formed in the lattice structure. A point in which a plurality of second pattern regions are bonded is located in the center of the first pattern region.
