Abstract

A transparent adhesive sheet for optics, which is capable of satisfying both adhesion and rework property, in view of the above problems of prior art. A production method of a silicone-based transparent adhesive sheet for optics for assembling the optical components, includes a step of forming a surface activation treated surface, in which peel strength after laminating onto an adherend increases with time, as compared with peel strength before lamination. The surface activation treatment is performed by using UV-ray irradiation on at least a part or the entire surface of an adhesive face contacting with the adherend of said transparent adhesive sheet for optics.
