摘要： A novel transparent double-sided adhesive sheet for image display device is provided, that, under the constraint of holding down the thickness of the adhesive sheet to 250 µm or less, can relieve a distortion arising within the adhesive sheet after laminating even if a member has a stepped portion of 50 µm to 100 µm in height on the laminating surface. Proposed is a transparent double-sided adhesive sheet for image display device which is used for the purpose of laminating an image display device constitutive member having on a laminating surface a stepped portion of 50 µm to 100 µm in height and a flat surface portion, and another image display device constitutive member, wherein a thickness of the maximum thickness portion of the adhesive sheet is 250 µm or less, and a gel fraction (a) at a position in contact with a stepped portion after laminating is 10% or greater and smaller than a gel fraction (b) at a position in contact with a flat surface portion.
