Claim Text:
1. An impact absorption member, comprising: an impact absorption sheet having an elastic material and including a plurality of bubble outlets penetratively extending completely through the impact absorption sheet in a thickness direction from a first surface of the impact absorption sheet that contacts an adhesive to a second surface of the impact absorption sheet, wherein the bubble outlets include a plurality of inclination areas inclined to have different inclination angles in the thickness direction such that light that penetrates the bubble outlets at one of the first surface and second surface is not visually observable through the bubble outlets at the other of the first surface or the second surface, wherein a cross section of each bubble outlet of the plurality of bubble outlets, as viewed in a plan view, has a circular form or a slit form, and wherein a width of the cross section of each bubble outlet, as viewed in the plan view, is smaller than or equal to T·tan θ, where T is a thickness of a portion of the impact absorption sheet corresponding to at least one of the inclination areas of the bubble outlet, and θ is an inclination angle of the inclination area with respect to a normal to the impact absorption sheet, and wherein each of the plurality of bubble outlets is discontinuous with adjacent bubble outlets within the impact absorption sheet.
