PROBLEM TO BE SOLVED: To provide an easy-to-open pouch which can prevent a weakened line from breaking at the terminal end in the cut direction. SOLUTION: The easy-to-open pouch with a pouring port 4 is formed with the weakened line 8 extending from one of seals 6 across a hollow part 5 to the end of the other seal 7. The side rim of a pouring port seal at the terminal end in the cut direction of the line 8 has a stress concentrated form 71a on which stress is concentrated. The terminal end in the cut direction of the weakened line 8 is positioned distantly from the stress concentrated form 71a. COPYRIGHT: (C)2004,JPO
