PROBLEM TO BE SOLVED: To provide a standing pouch with a spout, which is excellent in the balance of weight on both sides and suitable for high-speed filling when contents are filled through the spout which is held so as to turn vertical. SOLUTION: The internal line 43 of a bottom gusset seal part 33 is shaped like a hollow. The center line 50 of the spout 2 passes through a rising region 43c extending from the lowermost part 43a to the uppermost part 43b on the right-hand side in the internal line 43 of the bottom gusset seal part 33. A/B is substantially equal to C/D, wherein the overall width of the pouch body 1 is A; the overall height of the pouch body 1 is B; the height from the lower end of the pouch body 1 to the folding back part 30a of a bottom gusset part 30 is C; and the horizontal distance from the outermost part in the side edge on the left-hand side of the pouch body 1 to the position in the internal line 45 of the side edge seal part 35 on the left-hand side at the level of the folding back part 30a of the bottom gusset part 30 is D.
