PROBLEM TO BE SOLVED: To provide a fixing member capable of easily canceling a folded state. A fixing member according to an embodiment includes a first band portion, a second band portion, and a third band portion extending along a first direction, and a first band portion, a second band portion, and The third strip portion is set in a stacked state in which it is folded along the second direction intersecting the first direction and sequentially stacked. The fixing member includes a first coupling portion and a second coupling portion that maintain the stacked state. The first band portion and the second band portion are folded at a first bent portion located on one side in the first direction, and are separably coupled via a first coupling portion, The belt portion and the third belt portion are folded at the second bending portion located on the other side in the first direction, and the first belt portion has the coupling force of the first coupling portion and the coupling of the second coupling portion. It has a force synthesis inhibition part that inhibits the synthesis with force.
