PROBLEM TO BE SOLVED: To provide an unsealing history indicating band capable of enhancing the quality assurance function of the content in a container with a small bridge-breakage angle. SOLUTION: The unsealing history indicating band has a circumferential shape, and is provided on a lower end of a skirt part of a screw-fitting type cap via a breakable bridge. A plurality of flap pieces directing inwardly and upwardly or horizontally are provided on an inner surface of the band in a circumferential manner at predetermined intervals. Each flap piece is formed in a shape so that the length of a center part 17b in the circumferential direction at a tip part of each flap piece from the inner surface of the band is larger than the length of both end parts 17a in the circumferential direction from the inner surface of the band.
