PROBLEM TO BE SOLVED: To provide a method of forming a decorative coating having both superior artistic design properties due to metallic luster and radar beam transmittance which are equivalent to those obtianed, when using indium in spite of using metal lower in price than indium without using expensive indium, as to an exterior decoration disposed in a radar beam route of a radar device. SOLUTION: Aluminum is vacuum-deposited on the surface of a resin base material at a deposition rate of 300 μm/h to 500 μm/h, thereby forming the decorative coating thereon.

PROBLEM TO BE SOLVED: To provide a structure for mounting a solar battery module while reducing the number of parts and weight.SOLUTION: A solar battery module 2 is supported by a mounting plate 3 which is bent in an arch shape. The mounting plate 3 is connected to the solar battery module 2 at connection parts 11, 12 on both sides, and a mounting part 13 bends in an arch shape so that a mounting part is separated from the solar battery module 2. The mounting plate 3 generates an elastic force when a force acts on the solar battery module 2, to support the solar battery module 2. The solar battery module 2 is sufficiently supported by the elastic force, while the structure is significantly simplified, thereby reducing the number of parts and weight.
