We have measured the cross section for ฯ + ฯ -production in two-photon collisions using a data sample with an integrated luminosity of 85.9 fb -1 collected with the Belle detector. The f0(980) resonance is observed as a peak in the energy spectrum of the cross section. We also report preliminary res
