Experimental evidences of the charge ordering with the use of 13C-NMR techniques in various organic conductors are reviewed. In the insulating states of two-dimensional BEDT-TTF salts, a-I, and 8-RbZn(SCN)4, the formation of charge stripes perpendicular to molecular stacks are confiied. Charge disproportionation is estimated as 0.8:0.2 in the latter and more in the former. It is also observed that charge disproportionation already develops well above the MI transition temperature while no long-range charge order is stabilized. This seems to require a serious reconsideration of the transport properties in the `metallic' state.
