PROBLEM TO BE SOLVED: To provide a self-standing bag body in which the body member is separated into two layers through a separating layer provided on the body member constituting the self-standing bag body, and there exists a hole through which a content including a vaporizing substance can vaporizes in the body member after separation.
SOLUTION: The body member includes a first substrate layer/the separating layer/a second substrate layer. The first substrate layer includes at least a substrate with a resistance to piercing strength, and the second substrate layer comprises the substrate of at least one layer and a sealant layer in the innermost layer. The unsealed tab part with specified width and length is extended so that the body members of two sheets of surface and back at a specified position on the opening part side of the self-standing bag are projected from the end edge of a sealed part of the opening part. A half-cut line which does not penetrate through the first substrate layer from the sealant layer side is provided in the neighborhood of the end edge of the sealed part of the opening part, and the half-cut line is hooked through the tab part to separate the first substrate layer/the separating layer from the second substrate layer, and to have the hole penetrating the second substrate layer of the body member after separation.
