Abstract：
The pion's structure function behaviour is discussed by using the Fock state expansion of the hadronic wavefunction in QCD in this paper. As an example, we employ a model wavefunction of the Fock state in the light-cone and assume a Regge behaviour of a weight function for higher Fock states, and we get a possible form of the pion's structure function. This form is consistent with experimental data of the pion's structure function.
