Abstract
An impact sensing laminate 2 has a first surface 211 on which an impact force acts; a second surface 222 brought in contact with a protection object OBJ; an impact absorption layer 21 and a first pressure-sensitive layer 22. When a direction heading for the second surface from the first surface is defined as a first direction, the first pressure-sensitive layer is in the first direction from the impact absorption layer. The first pressure-sensitive layer is a layer of sensing a first impact force as the impact force to have been attenuated by the impact absorption layer.
