A hexagonal cube corner retroreflective article has a set of a large number of hexagonal cube corner retroreflective elements. In the retroreflective element, at least one reflective lateral face (face a, face b, and/or, face c) is divided into a pair of an upper secondary reflective lateral face (face a1, face b1, and/or face c1) and a lower secondary reflective lateral face (face a2, face b2, and/or face c2) partitioned by a line segment (EF, FD, and/or DE) connected by apexes (E, F, and/or D) constituting that reflective lateral face, in which two secondary reflective lateral faces constituting the pair of the secondary reflective lateral faces are not on the same plane. By these features the retroreflective article provides excellent observational angle characteristics.
