The power dependence in the inclusive k_T-distribution in the large k_T-region is derived in the extended hadron model of Nielsen and Olesen without relying upon hard scattering of hadron constituents. The k_T-dependence behaves like 〜-ln k_T when k_T is small, then it becomes exp[-γk_T] in the medium k_T region (k_T≲1.5(GeV/c)), and further it changes to behave like (k_T)^<-n(k_T)>, when k_T becomes much larger. Our k_T-dependence is consistent with the experimental data. This k_T-distribution is derived by the strong repulsive force between two vortex lines (identified as hadron). This repulsive force is caused by the pressure of the spontaneouly broken vacuum state which is necessary to confine the vector field. Our model on the k_T-distribution is very analogous to the production of massive resonances and their successive decay.
