A pouch with a spout includes a pouch body 1 formed by overlapping and thermally fusing both end portions, forming a seam, of a flexible film material and a spout 3 to be inserted between the film end portions of the pouch body 1 and then thermally fused together with the film end portions to the pouch body, wherein a stress dispersion patch 4 is bonded so as to cover partially both a spout seal portion 2 and a deformable film portion 5 so as to straddle a boundary portion 6 between the spout seal portion 2 and the deformable film portion 5 facing an inner space of the pouch body 1.
