Electromagnetic wave transmissive metal member, article using the same, and production method for electromagnetic wave transmissive metal film

Abstract

Provided is an electromagnetic wave transmissive metal member capable of being easily produced at a low production cost, with both a metallic luster and an electromagnetic wave transmissibility, an article using the electromagnetic wave transmissive metal member, and a production method for an electromagnetic wave transmissive metal film. The electromagnetic wave transmissive metal member comprises a metal layer and a crack layer, wherein the metal layer and the crack layer have, in their respective planes, a plurality of linear cracks extending substantially parallel to each other. The linear cracks in the metal layer and the linear cracks in the crack layer penetrate through their respective layers in a thickness direction, and are continuous with each other in the thickness direction.

Dependencies are inferred from the claim text.
