Energy spectra of charged $\pi$-mesons produced in C, Al and Cu bombarded by a 345 MeV proton beam were obtained with nuclear emulsions. The production cross sections of $\pi^{+}$- and $\pi^{-}$-mesons from aluminium are ($5.3\pm 1.2$) $10^{-28}$cm2 ster. -1 and ($1.9\pm 0.8$) $10^{-28}$ cm2 ster. -1 respectively. In case of copper they are ($1.2\pm 0.2$) $10^{-27}$cm2 ster. -1 and ($3.6\pm 1.0$) $10^{-28}$cm2 ster. -1 respectively. Comparing with the cross section of $\pi$-mesons from carbon obtained by Richman et al. it is found that the cross section for charged $\pi$-meson production varies roughly as mass number A for small A.
