The point-contact Andreev-reflection measurements on the new paramagnetic superconductor Mo_3Sb_7 were carried out. It was found that the order parameter ∆ is strongly anisotropic varying over a very wide range depending on the contact orientation when the maximum ∆_{max} exceeds at least 40 times the minimum ∆_{min} in spite of the invariable T_c that cannot be typical of conventional superconductors. For these and other reasons we suggest that Mo_3Sb_7 is not a trivial BCS (s-wave) superconductor but rather has some unconventional pairing symmetry.
