To provide a pocket structure and a bag capable of suppressing mixing of a foreign matter into a pocket, and suppressing unintended discharge of a stored object to the outside even when a lid of the pocket is opened by an unintended external force.SOLUTION: In this pocket structure, the first upper end side 121u of the first 122u surface portion 121 is located above the second upper end side 122u of the second L1 surface portion 122, and a bending line side wall for bending the first wall surface portion 121 and the second wall surface portion 122 to the outside of the second wall surface portion 122 is provided at a position below the second upper end side wall of the first wall surface portion 121 and the second wall surface portion 122. A first state in which the opening S1 of the internal space S is opened by lifting the first wall surface part 121 upward, and a second state in which the opening S1 is closed by bending the first wall surface part 121 and the second wall surface part 122 to the outside of the second wall surface part 122 along the bending line L1 can be selected.SELECTED DRAWING: Figure 6
