摘要： A retroreflective object having a retroreflective clement layer in which a large number of cube corner retroreflective elements of total internal reflection type are disposed. In the back surface of the retroreflective element layer, an optical characteristic adjusting layer is partially provided, and in the back surface of the optical characteristic adjusting layer, an air layer is provided. With the invention, an optical characteristic adjusting layer for adjusting a hue and occupant area ratio can be provided on the back surface of the retroreflective element layer of an existing object in a simple way for easy adjustment, thus enabling a retroreflective object to be manufactured at high productivity and low cost. Therefore, retroreflective objects suitable for reflective plates for traffic related signs such as a traffic sign, a regulation sign, an information sign, and a construction work sign, commercial sings, and reflected-light sensors for visible light, laser beam, or infrared light can be manufactured effectively with use of existing products.
