A heat-ray-blocking fluororesin film includes a heat-ray-blocking metal oxide and a hydrotalcite-type compound represented by Chemical Formula [1], wherein the content of the hydrotalcite-based compound is 0.03 to 1.0 wt %. The heat-ray-blocking fluororesin can exhibit excellent heat-ray-blocking performance while keeping the properties inherent in fluororesin films such as mechanical properties, transparency and long-term weatherability and is transparent and can be used out of doors for a long period of time, wherein Mg2+1−a.Al3+a(OH−)2.ANn−a/n.cH2O where 0.2≤a≤0.35 and 0≤c≤1; ANn− indicates n-valent anion.
