Abstract
A coating layer having an anti-ultraviolet effect and impact resistance is provided on a surface of a resin film to form a protective film, and the protective film is bonded to a surface of an ultrasonic sensor, so that it is possible to protect the ultrasonic sensor from an impact caused by a flying stone or the like without impairing the ultrasonic transmission and reception capability of the ultrasonic sensor. By providing a hard coat layer having an anti-ultraviolet effect on a surface of the protective film, it is possible to prevent yellowing caused by ultraviolet rays, and to prevent deterioration of the characteristics of the sensor due to peeling of the protective film. A colored layer is formed by stacking a plurality of layers of ink that is toned to the same color as a vehicle exterior component, thereby ensuring design.
