In this research the effect of thickness on the A.C electrical conductivity of CuO thin films have been studied at room temperature and at different thickness ( 1500, 1800, 2000 ,2500 ) A .
The films were prepared using the method of chemical spray pyrolysis on glass substrate heated to (653 K ).
The results showed that there were increasing in A.C electric conductivity when thin film thickness and the frequency have been increased.
Another conclusion can be noticed, that the capacitance, the imaginary part of dielectric constant and the lose factor were decreases with the increasing of the frequency , while they were increases by mean of increasing thickness ,while the real part of dielectric constant were decrease when the thickness and the frequency increased .
