The anisotropic transfer integrals characterizing the quasi-one-dimensional (Q1D) electronic structure are determined experimentally for the new organic superconductor (DMET)_2CuCl_2 by angle-dependent magnetoresistance and polarized reflectance measurements. Lebed resonances and third angle effect are observed in the angle-dependent magnetoresistance; the latter gives the ratio of the inter- and intra-stack transfer integrals as t_{a'} / t_b=0.1. From the anisotropy of the plasma frequency found in the polarized reflectance spectra, the intraand inter-stack transfer integrals are deduced as t_b=0.28 eV and t_{a'}=0.028 eV, respectively, in good agreement with the results of the third angle effect. The observed anisotropy of the transfer integrals is the same as those for the Q1D TMTSF salts, which is consistent with the appearance of the field-induced spin-density-wave states at magnetic fields similar to those of the Q1D TMTSF salts.
