PURPOSE:To obtain a reflecting tube having excellent corrosion resistance and whose radio wave transmitting characteristic is unchanged for a long period by forming the reflecting tube that a coating film with excellent weather resistance, the metallic layer and the olefinic polymer layer are laminated sequentially. CONSTITUTION:The thickness of the coating film layer with excellent weather resistance being an inner layer is 5mu-1mm., the thickness of the metallic layer being an intermediate layer is 5mu-1mm., and the thickness of the olefinic polymer layer being an outer layer is 0.5mm.-15mm.. As a typical example of a paint 1, an unsaturated or a saturated polyester resin group paint is used. As a typical example of a metal 2, a metal simple substance or an alloy such as aluminum, iron, copper or zinc is used. As the olefinic polymer 3, ethylene homopolymer, a propylene homopolymer, or an ethylene and propylene copolymer is used. |
