We present photometric and spectroscopic observing results of the oEA star IV Cas. Spectral types of the binary system are derived to be A3 (T_{eff} = 8500 K) for the primary component and G9 (T_{eff} = 5370 K) for the secondary. We detected two δ Scuti-type pulsation frequencies of f_1 = 32.6894 c/d (cycles per day) and f_2 = 36.6714 c/d, for the primary component.
