The high melting point of copper (1083 °C) explains why the resistivity of the pure liquid is not well known. Important differences exist between the scarce old data. In this paper new accurate measurements are presented and the temperature dependence of the resistivity is discussed in the framework of Ziman's formalism in terms of structure factor and form factor. Both, experimental (obtained by neutron scattering experiments) and calculated (following a hard sphere description) structure factors are used. The form factor is deduced from model pseudo‐potentials which take into account the d band like the Moriarty (1972) potential or from the t matrix expressed in terms of phase shifts. The different calculations lead to a fairly good agreement.
