ELECTROMAGNETIC WAVE TRANSMITTING LUSTROUS RESIN PRODUCT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave transmitting lustrous resin product and a method for manufacturing the electromagnetic wave transmitting lustrous resin product having electromagnetic wave transmitting property while having lustrous property by containing a chromium film of discontinuous structure.

SOLUTION: The electromagnetic wave transmitting lustrous resin product contains a resin base material 11 formed of polycarbonate (PC), and an aluminum (Al) film 13 formed on the resin base material 11 by sputtering. The chromium film 12 is formed on the aluminum film 13 by sputtering and then heated together with the resin base material 11 at 120°C for two hours to form a discontinuous structure film of the aluminum film 13 and chromium film 12.
