The iso-singlet scalar resonance \sigma(600), found in the recent \pi\piphase shift analysis, is pointed out to have the properties of the \sigma mesonin the \sigma model. The role of the \lambda\phi^4 interaction as a source ofthe ``background phase", which was essential there, is also discussed.Comment: 4pages, Latex with Prog.Theor.Phys. format PTPTEX.sty, no figures, to be published in Prog.Theor.Phys.96(1996
