An object of the present invention is to provide a laminate of a void layer and a pressure-sensitive adhesive layer in which adhesive strength or adhesive strength is satisfied, and an adhesive agent or an adhesive agent does not easily penetrate into the voids. In order to achieve the above object, the first laminate of the present invention is characterized by comprising a void layer (20) and an adhesive bonding layer (30), wherein the adhesive adhesive layer (30) is directly laminated on one side of the void layer (20). or both sides, the void ratio of the void layer (20) is 35% by volume or more, and after the heating and humidifying durability test at a temperature of 85° C. and a relative humidity of 85% for 500 hours, the void remaining ratio of the void layer (20) is the above heating and humidifying. 50 vol% or more before the durability test. |
