PROBLEM TO BE SOLVED: To enable, when an abutting portion formed on a target progresses between two caps, the realization of a buffer function by avoiding the bottoming thereof at a valley bottom.SOLUTION: A laminate cellular sheet 1 includes at least a cap film 21 possessing many hollowly bulging caps 211 and a back film 22 laminated on the cap-opening side of this cap film 21. In a case where, on a representation of the laminate cellular sheet 1 viewed from the cap bulging side, a circle contacting the respective circumferential planes of three or more mutually adjacent caps 211 is defined as a circumferentially contiguous circle S, a point at which this circumferentially contiguous circle S is contacted with the circumferential plane of each cap 211 is defined as a circumferential contact point P, and the distance between two circumferential contact points P specific to one circumferentially contiguous circle S is defined as an inter-circumferential-contact-point distance W, this inter-circumferential-contact-point distance W is equal to or lesser than a length ascertained by multiplying the height of the cap 211 along the bulging direction by 2/3. |
