Damping body for packaging and package body

A damping body for packaging includes, between an abutment adapted to abut against a precision substrate storage container upon packaging and an outer peripheral wall rising from an outer peripheral edge of a bottom part having the abutment, an outer peripheral bottom formed at a position distanced more from the abutment than is the precision substrate storage container, and a stepped part formed between the outer peripheral bottom and the abutment. Consequently, in the event of an impact from the outside, the stepped part collapses, so that the abutment favorably moves with respect to the outer peripheral bottom and thus can efficiently absorb the impact. This can prevent large impacts from instantaneously being exerted on the precision substrate storage container and efficiently damp drop impacts.
