Abstract: A sheet material container includes a container body that surrounds a containing portion for accommodating a content. The container body is formed of a container body-forming sheet member formed by layering a plurality of base material films. The container body-forming sheet member includes the plurality of base material films, an attaching layer by which the base material films are attached to each other, and a filler enclosed portion that is formed between the plurality of base material films and into which a filler is to be filled. The plurality of base material films are made from the same type of resins.
