Abstract: Object:
A plurality of problems of an electromagnetic wave transmissive cover to be installed in an electromagnetic wave irradiation direction of a sensor using an electromagnetic wave are simultaneously eliminated.
Resolution means:
An electromagnetic wave transmissive cover 1 is a member to be installed in an electromagnetic wave irradiation direction of a millimeter wave radar 100 using an electromagnetic wave, and includes a colored resin member 3, a transparent resin member 5, and a transparent heater film 7. The transparent resin member 5 is provided on an opposite side to the millimeter wave radar 100 of the colored resin member 3. The transparent heater film 7 is provided on the opposite side to the millimeter wave radar 100 of the colored resin member 3, includes a wiring pattern formed by copper plating or etching, and has electromagnetic wave transmissivity.
