Zusammenfassung:	To provide a laminate that achieves tacky strength or adhesive strength, while achieving less penetration of a tackiness agent or an adhesive agent into voids of a void layer.SOLUTION: A laminate of the invention includes a void layer and a tacky adhesion layer. The tacky adhesion layer is directly laminated on one face or both faces of the void layer. The tacky adhesion layer is made of a tacky adhesive agent containing a (meth) acrylic polymer and an oligomer-type silane coupling agent. The content of the oligomer-type silane coupling agent is 1 pt.mass or less relative to 100 pts.mass of the (meth) acrylic polymer.SELECTED DRAWING: Figure 1 【課題】本発明は、粘着力または接着力と、空隙層の空隙への粘着剤または接着剤の浸透しにくさとを両立した積層体の提供を目的とする。【解決手段】本発明の積層体は、空隙層と、粘接着層とを含み、粘接着層が、空隙層の片面または両面に直接積層されており、粘接着層が、（メタ）アクリル系ポリマー及びオリゴマー型のシランカップリング剤を含む粘接着剤により形成され、オリゴマー型のシランカップリング剤の含有量が、（メタ）アクリル系ポリマー１００質量部に対して１質量部以下であることを特徴とする。【選択図】図１
