In order to analyze trace metals by Atomic absorption spectrophotometer in infant formula milk powder, Wet digestion method using nitric acid, perchloric acid mainly and D.D.T.C.-M.I.B.K. extraction method were done. The r-value of calibration curve were more than 0.999 in Cu, Mn, Zn. Recovery test showed high recovery rate of $97-104\%$. The results were as follows: Averages of total samples were Cu $1.92pm1.24 ppm,;Mn;1.18pm1.01ppm,;Zn;22.43pm8.88ppm.$ Averages of Common Infant formula were Cu1.96pm1.26ppm,;Mn;1.0pm0.57ppm,;Zn;21.52pm9.72ppm.$ Averages of follow-up infant formula were Cu$1.89pm1.26ppm,;Mn;1.36pm1.31ppm,;Zn;23.34pm8.7 ppm.$
