A method for producing a layered article is provided which is capable of achieving a sufficient production rate, and which is preferably capable of suppressing variation in weld strength, and reducing variation in product quality. In this method for producing a layered article, ultrasonic welding is used to weld at least a portion of a single-layer body or a stacked body provided with at least one layer including a fibrous non-woven fabric having a fibre diameter of not more than 100 µm.
