• A calculation of the electrical conductivity of alkali metals is carried out within the limit of the one-electron approximation. The band structure obtained by Ham and the phonon spectrum detemined by experiments are taken into account in the calculation. The absolute values of the conductivity of Li, Na and K at room temperature are evaluated and compared with experiments. The agreement between the theory and the experiment is reasonably good. The temperature dependence of their conductivity is evaluated. In the case of potassium the agreement between the theory and the experiment is quite good down to the very low temperature. In the other two cases, the agreement is reasonably good down to 80°K, but becomes worse at low temperatures. The pressure dependence of their conductivity is also evaluated. The theoretical values dlnp/dln V of Li, Na and K are -1.7, 4.4 and 5.1, while the observed values are -O.7, 4.4 and 5.5, respectively.
