Abstract:
A lens pad includes a blank, first adhesive layer, and release sheet. The first adhesive layer is formed on one surface of the blank. The release sheet comes into tight contact with the surface of the first adhesive layer to protect this surface. The arithmetic average roughness of the surface of the release sheet on the side of the first adhesive layer is 0.1 μm or less. The surface of the first adhesive layer from which the release sheet is peeled off is attached onto a lens as an edging target. A lens pad, a lens pad manufacturing method, a lens manufacturing method, and an adhesive member are also disclosed.
