Abstract: A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. An outline of a communication part that extends from the hole to the outer edge of the pouch includes a first line and a second line. The communication part includes a first portion and a second portion. The first position includes a portion where the first line and the second line have a spacing from each other that decreases with increasing distance from the outer edge of the pouch toward the hole. The second portion is located between the first portion and the hole, and includes a portion where the first line and the second line have a spacing from each other of less than or equal to 2.0 mm.

Abstract: A first packaging material includes at least one layer located in both a first region and a second region. A second packaging material includes at least one layer located in both the first region and the second region. The hole includes a proximate position where the distance between the hole and the outer edge of the pouch in a center-of-gravity direction is shortest, the center-of-gravity direction being a direction in which a center-of-gravity line passing through the center of the pouch and the center of the hole extends. A communication part is connected with the hole at a position that is spaced apart from the proximate position in a direction orthogonal to the center-of-gravity direction. The outline of the communication part that extends from the hole to the outer edge includes a first line and a second line. The first line is located closer to the proximate position than is the second line. In the center-of-gravity direction, the distance from a first connection point to the outer edge is greater than the distance from the proximate position to the outer edge, the first connection point being a point where the first line is connected with the hole.
