To provide a sign tape retaining high reflecting luminance for a long time without losing its retroreflective ability, hardly deteriorated under an especially sever natural environment such as a cold region, and to provide a delineator stuck therewith.

This sign tape comprises a belt-shaped reflecting tape 4a having the retroreflective ability to an incident light and a transparent resin tape 4b integrally stacked on the reflecting surface side of the reflecting tape 4a and capable of covering, at least, the whole surface of the reflecting tape 4a and the transparent resin tape 4b has the thickness of 50-200 μm and the all light transmission factor of, at least, 90% or more. This delineator is stuck therewith.
