We report on resistivity and susceptibility measurements of the superconducting Nb1-xTaxSe3 single crystals with 0.14≤x≤0.16. Its crystal structure is the same as that of NbSe3 and the highest Tc is 6 K at x = 0.15. The measurements of the upper critical field Hc2 revealed the quasi two-dimensional nature and the angular dependence of Hc2 is consistent with the anisotropic effective mass model.
