Abstract
We discuss internal structure of an exotic hadron by using fragmentation functions. The fragmentation functions for the f₀(980) meson are obtained by a global analysis of e^++e^- → f₀+X data. Quark configuration of the f₀(980) could be determined by peak positions and second moments of the obtained fragmentation functions.
