We present both binarity and pulsation of KIC 6220497 from the {\it Kepler}observations. The light curve synthesis shows that the eclipsing system is asemi-detached Algol with parameters of $q$ = 0.243$\pm$0.001, $i$ =77.3$\pm$0.3 deg, and $\Delta T$ = 3,372$\pm$58 K, in which the detachedprimary component fills its Roche lobe by $\sim$87\%. A multiple frequencyanalysis of the eclipse-subtracted light residuals reveals 33 frequencies inthe range of 0.75$-$20.22 d$^{-1}$ with amplitudes between 0.27 and 4.56 mmag.Among these, four are pulsation frequencies in fundamental ($f_1$, $f_5$) and$p$ ($f_2$, $f_7$) modes, and six are orbital frequency ($f_8$, $f_{31}$) andits harmonics ($f_6$, $f_{11}$, $f_{20}$, $f_{24}$), which can be attributed totidally excited modes. For the pulsation frequencies, the pulsation constantsof 0.16$-$0.33 d and the period ratios of $P_{\rm pul}/P_{\rm orb}$ =0.042$-$0.089 indicate that the primary component is a $\delta$ Sct pulsatingstar and, thus, KIC 6220497 is an oscillating eclipsing Algol (oEA) star. Thedominant pulsation period of 0.1174051$\pm$0.4 d is significantly longerthan that expected from empirical relations that link the pulsation period withthe orbital period. The surface gravity of $\log g_1$ = 3.78$\pm$0.03 isclearly smaller than those of the other oEA stars with similar orbital periods.The pulsation period and the surface gravity of the pulsating primarydemonstrate that KIC 6220497 would be the more evolved EB, compared with normaloEA stars.
