  The bremsstrahlung flux-averaged cross-sections $\langle{\sigma(E_{\rm{\gamma
max}})}\rangle$ for the photonuclear reactions
${^{65}\rm{Cu}}(\gamma,n)^{64}\rm{Cu}$, ${^{63}\rm{Cu}}(\gamma,n)^{62}\rm{Cu}$,
${^{63}\rm{Cu}}(\gamma,2n)^{61}\rm{Cu}$ and
${^{63}\rm{Cu}}(\gamma,3n)^{60}\rm{Cu}$ have been measured in the range of
bremsstrahlung end-point energies $E_{\rm{\gamma max}}$ = 35-94 MeV.
  The experiments were performed with the electron beam from the NSC KIPT
linear accelerator LUE-40 with the use of the activation and off-line
$\gamma$-ray spectrometric technique. The calculation of the flux-average
cross-sections $\langle{\sigma(E_{\rm{\gamma max}})}\rangle_{\rm{th}}$ was
carried out using the cross-section $\sigma(E)$ values from the TALYS1.95 code
with the default options.
  It is shown that the experimental average cross-sections for the reactions
${^{65}\rm{Cu}}(\gamma,n)^{64}\rm{Cu}$, ${^{63}\rm{Cu}}(\gamma,n)^{62}\rm{Cu}$,
${^{63}\rm{Cu}}(\gamma,2n)^{61}\rm{Cu}$ are systematically higher than the
theoretical estimates in the TALYS1.95 code. The obtained
$\langle{\sigma(E_{\rm{\gamma max}})}\rangle$ supplement the data of different
laboratories for the case of reactions $(\gamma,n)$ and $(\gamma,2n)$. For the
reaction ${^{63}\rm{Cu}}(\gamma,3n)^{60}\rm{Cu}$, the values of
$\langle{\sigma(E_{\rm{\gamma max}})}\rangle$ were measured for the first time.
