Abstract: To provide a spouted pouch with a simple structure and improved self-standing ability of the pouch body. The spouted pouch 10 is configured to dispense a liquid content from a spout 60 attached to a side face of a pouch body 20 in a state placed with a pouch bottom 20a down. The pouch body 20 further includes a first shape-controlling seal portion 24 formed by heat sealing a first film 30 and a side film 40 together at a location on an inner side of a first side seal 23a in the left-right direction. The first shape-controlling seal portion 24 has an area located in a region between an upper half of a spout fixture portion 32 and the first side seals 23a, and does not have an area located below the center in the up-down direction of the spout fixture portion 32.
