NGC 6716 is an intermediate-age open cluster in Sagittarius. In this paper, we present the new UBV CCD photometry of the stars in the cluster, which is deeper than previous ones. From the color-color diagram and the color-magnitude diagram, we derived a reddening $E_{B- V} = 0.17pm0.03$ and a distance modulus of the cluster, $(V - Mv)_o = 9.2pm0.1$. An age of the cluster is estimated as $8pm10^7 yrs$ from the latest isochrone. Luminosity function and mass function of the cluster are derived. The gradient of the mass function of bright stars is a bit steep, $Gamma = -1.85pm0.05$, and there is no distinct bump and dip in the mass function.
