摘要:
An optical element includes glass substrates adhered to surfaces of a birefringent material film through an adhesive. The optical element has a coating for moisture-proof. The moisture-proof treatment is performed by applying a mixed solution of a soluble fluorine resin and an ethylenic compound to end surfaces of the glass substrates and the birefringent material film. Otherwise, the optical element is dipped in a solution prepared by mixing a soluble fluorine resin and an ethylenic compound in a predetermined mixing ratio, so as to moisture-proof the end surfaces of the glass substrates and the birefringent material film. The birefringent material film is a phase difference film. The soluble fluorine resin is an amorphous fluorine resin. The ethylenic compound is PTFE.

Internal electrode layers are superimposed in a dielectric substrate 1 at intervals. Step absorption layers are respectively provided on lateral sides of the internal electrode layers. A side portion of the internal electrode layer forms an inclined surface, and the step absorption layer is superimposed so as to partially overlap the inclined surface of the internal electrode layer. This is also applied to the other internal electrode layers and step absorption layers.
