Abstract: The present invention provides an optical element, an optical element wafer and a method of manufacturing the same. The optical element comprises a optical film adhered on an substrate of the optical element. The method for manufacturing the optical element wafer comprising the steps of dividing a base material of a optical film into a plurality of optical films, separating the optical film base material by removing sections where no optical film is to be formed, adhering the divided optical films on the substrate base material, and a plurality of optical elements are obtained by dividing the substrate base material with the optical film adhered on one surface of the individual substrate.

Abstract: Disclosed is wrapped glass cap article, comprising at least one glass cap and a pair of plastic films having located therein the at least one glass cap, at least one of the pair of plastic films being imparted on its inner surface with a weak adhesiveness so that the glass cap is tightly sealed due to the weak adhesiveness of the plastic film. The article gives rise to glass caps with less contamination when the plastic film is peeled off.
