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.

Abstract: A metallic lustrous member with radio wave transmissibility is provided, which is capable of being easily produced, while ensuring a structure in which not only chromium or indium but also any of some other metals such as aluminum is formed as a metal layer on a continuous surface of any of various materials, and also an article using the member is provided. A production method for a metallic lustrous member with radio wave transmissibility, which is capable of easily forming, as a metal layer, not only chromium or indium but also any of some other metals such as aluminum, on a continuous surface of any of various materials. The metallic lustrous member comprises a substrate having radio wave transmissibility, and an aluminum layer formed directly on a continuous surface of the substrate. The aluminum layer has a discontinuous region including a plurality of separated segments which are mutually discontinuous.
