An analysis is presented of both weak and strong lines of Mn I with well-defined profiles in the solar photosphere, using the accurate oscillator strengths measured at Oxford. In an LTE analysis with the Holweger and Mueller (1974) model solar atmosphere a manganese abundance of log A = 5.39 at a microturbulence value of 0.85 km/s is found for the disk center. Comparison of this result with the Oxford determination for the solar iron abundance shows an interesting discrepancy with the Fe/Mn ratio found in type C I meteorites.
