The method for manufacturing a bag involves performing a step for bending a strip-shaped body, which is to be a bag, with a first bendable part (21) as a center such that a second end (12) overlaps the first main surface. Furthermore, a step is performed for bending the strip-shaped body with a second bendable part (22) as a center such that a first end (11) overlaps a second main surface (14). A step is performed for obtaining a laminate by bending the strip-shaped body with a third bendable part as a center such that the first bendable part (21) is adjacent to the first end (11). Furthermore, a step is performed for fixing a portion of the strip-shaped body at both end portions of the laminate in a direction intersecting the extension direction of the strip-shaped body. Furthermore, a step is performed for turning over the laminate body from a first opening part (41) such that the second end (12) is exposed to the outside and the first main surface of the second bendable part (22) is exposed to the outside. Furthermore, a step is performed for turning over the laminate again from a second opening part (42) in the turned-over laminate.
