A pouch and a production method for a spout pouch container are provided, which suppress curling of an opened spout attachment edge portion and offset of a filling port defining edge portion adjacent to the spout attachment edge portion when a spout is heat-sealed to the spout attachment edge portion. The pouch () is of a bottom gusset type, which includes a pair of front and rear exterior sheets () and a gusset sheet () folded inward from lower portions of the exterior sheets () to define a bottom gusset portion. When a spout () is attached to the pouch (), a spout attachment edge portion (A) and a filling port defining edge portion (B) disposed adjacent the spout attachment edge portion (A) and defining a filling port through which a liquid product is filled as content in the pouch are unsealed, but a spot-seal portion (PS) formed by partly heat-sealing the pouch is disposed in a region around a boundary between the spout attachment edge portion (A) and the filling port defining edge portion (B).
