An NQR experiment revealed superconductivity of Pr2Ba4Cu7O15-\delta (Pr247) to be realized on CuO double chain layers and suggests possibility of novel one-dimensional (1D) superconductivity. To clarify the nature of the 1D superconductivity, we calculate the band dispersions of Pr247 by using the generalized gradient approximation (GGA). It indicates that Fermi surface of CuO double chains is well described to the electronic structure of a quasi-1D system. Assuming the zigzag Hubbard chain model to be an effective model of the system, we derive tight binding parameters of the model from a fit to the result of GGA. Based on the Tomonaga--Luttinger liquid theory, we estimate transition temperature (T_{\text{c}}) of the quasi-1D zigzag Hubbard model from the calculated value of the Luttinger liquid parameter K_{\rho}. The result of T_{\text{c}} is consistent with that of experiments in Pr247 and it suggests that the mechanism of the superconductivity is well understood within the concept of the Tomonaga--Luttinger liquid.
