We have carried out inclusive measurements of Λ(Λ) production in two-photon processes at TRISTAN. The mean √(s) was 58 GeV and the integrated luminosity was 265 pb-1. Inclusive Λ(Λ) samples were obtained under such conditions as no-electron, anti-electron, and remnant-jet tags. The data were compared with theoretical calculations. The measured cross sections are two-times larger than the leading-order theoretical predictions, suggesting the necessity of next-to-leading-order Monte-Carlo generator.
