The present invention provides a sterically hindered phenyl group-containing phosphonate compound, a production method thereof, and a flame-retardant polycarbonate resin composition containing the same. A sterically hindered phenyl group-containing phosphonate compound represented by the following chemical formula (1), a method for producing the same, and a flame retardant polycarbonate resin composition containing the same. In the chemical formula (1), R 1 is a C 1 -C 6 linear or branched alkyl group or a C 6 -C 14 aryl group, R 2 is a C 1 -C 6 linear alkyl group, or a branched alkyl group of C 3 -C 6, n are each independently an integer of 1 to 3.
