The present invention provides a sheet material container (90) being made of a sheet material (20) and including a body portion (12) and a bottom portion (25) that is to be disposed on a placement surface, and the sheet material (20) including a plurality of film layers (20a,20b, and 20c). A body portion sheet (93a) that constitutes the body portion (12) includes a bonding portion (94) where peripheral edge portions of the sheet materials (20) are bonded. In a bottom surface sheet (93b) that constitutes the bottom portion (25), a non-adhesive region (99) is provided in the plurality of film layers (20a, 20b, and 20c). The non-adhesive region (99) forms a bottom filler-filled portion (96b). The bottom filler-filled portion (96b) extends annularly around a non-filled portion (96j), and includes at least three protruding leg portions (96m) that are to be placed on the placement surface so as to allow the container (90) to stand by itself. The protruding leg portions (96m) protrude toward the placement surface past other portions in the bottom filler-filled portion (96b) due a leg forming portion (100)
