A cylindrical cavity resonator of TE_<013> mode was constructed and Its Q value was measured at the frequency of 3075 Mc/sec. It was found that the Q-value is reduced, when the end-plate of the cavity is slightly tilted. The optimum Q-value (Qv=7.53×10^4) agrees well to that calculated from the d.c. conductivity of the wall material (copper). It may be considered that some other modes (TE_<11>, TE_<12> and TM_<11> modes) of waves are generated from the primary. TE_<91> mode and they are lost as heat and radiation, when the end-plate is tilted. Thereby the resonance of TE_<01> mode is damped by mode conversion which is calculated assuming the deformation of the cavity wall is small. The calculated result agrees well to the observed Q-value of the cavity with tilted end-plate.
