It is intended to provide a metallic lustrous member with radio wave transmissibility, which is capable of being easily produced, while ensuring a structure in which not only chromium (Cr) or indium (In) but also any of some other metals such as aluminum (Al) is formed as a metal layer on a continuous surface of any of various materials, and an article using the member. It is further intended to provide a production method for a metallic lustrous member with radio wave transmissibility, or an article using the member, which is capable of easily forming, as a metal layer, not only chromium (Cr) or indium (In) but also any of some other metals such as aluminum (Al), 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.
