Abstract

An adhesive tape which is to be arranged between a lens and at least one of a plurality of chucks in an edge-machining apparatus comprises an adhesive face for being in contact with the lens. A measurement of an adhesive strength of the adhesive face is 4 gf (0.0392 N) or more when a polyethylene terephthalate plate which has been subjected to a surface treatment with a fluorine-modified silicone parting agent is used as a test plate in an adhesive strength test method based on a 180°-peeling method as defined in JIS Z 0237 'adhesive tape/adhesive sheet test method'. A technique which can be used to edge the lens in which an antifouling layer is formed by using a fluorine-containing silane compound having an excellent antifouling effect is also provided.
