摘要：
Provided are: a multilayer structure having a strong initial interlayer adhesive force, with a decrease of the interlayer adhesive force being prevented even in a case of use in a harsh environment such as exposure to hot water, an acid, or an alkali for a long period of time; a method for producing such a multilayer structure; and a sheet for preventing diffusion of hazardous substances, a landfill geomembrane, and a multilayer pipe, each including such a multilayer structure.
