A retroreflective function member exhibits better retroreflective properties than a cube corner type retroreflective function member, which e has conventionally excelled most in the retroreflective properties is provided. The retroreflective function member is formed by injection molding transparent acrylic resin to provide a substantially plate-shape of which the upper surface, the bottom surface, and right and left surfaces are flat. The front surface is adapted to serve as the incoming and outgoing surfaces and aluminum is deposited on the rear surface to be used as a reflective surface. The outside of the rear surface is protected by a resin. |
