Abstract: The present disclosure provides a radio wave transmissive metallic member having an excellent metallic luster. The present disclosure relates to a metallic member and a method for manufacturing the same. The metallic member comprises a substrate body, an ion-exchange resin layer formed on the substrate body, and a metal particle layer formed on the ion-exchange resin layer, wherein metal particles having a high aspect ratio are longitudinally oriented with respect to the ion-exchange resin layer and the substrate body.

Abstract: Provided is a new board with a sufficient adhesion strength between an insulating layer and a metal layer. A board of the embodiment is a board including an insulating layer and a metal layer. The insulating layer contains a resin containing an insulating filler. The metal layer is disposed on a surface of the insulating layer. The resin is present partially between at least a part of the insulating filler present in the surface of the insulating layer and a metal constituting the metal layer. In an interface between the insulating layer and the metal layer, a depth of the metal present at a deepest portion in the insulating layer is 1.2 µm or less based on the resin or the insulating filler present in an outermost surface of the insulating layer.
