Abstract
An object of the present invention is to provide an electromagnetic wave penetrative metal film having high mass productivity and an extremely low attenuation rate in the electromagnetic wave penetrated through, a manufacturing method of the electromagnetic wave penetrative metal film, and a radome for a vehicle-mounted radar devices using the electromagnetic wave penetrative metal file. To achieve the object, the present invention provides an electromagnetic wave penetrative metal film composed of more than 10000 of fine metal film pieces per unit area (1 mm) provided on a surface of a substrate through an electroless plating step, wherein fine metal film pieces adjacent to each other are electrically isolated, a manufacturing method of the electromagnetic wave penetrative metal film, and a radome for a vehicle-mounted radar devices using the electromagnetic wave penetrative metal film.
