The detailed features of the structural disorder in superconducting oxides with T*-structure, Nd{single bond}Ce{single bond}Sr{single bond}Cu{single bond}O and La{single bond}Sm{single bond}Sr{single bond}Cu{single bond}O, have been investigated as diffuse scattering observed in electron diffraction patterns. There exist three types of characteristic diffuse scatterings: cylindrical-shape, spike-shape, and spotty scatterings in (Nd_0.8-xCe_xSr_0.2)₂CuO_z with the T*-structure while only a cylindrical-shape scattering exists in (La_0.9-xSm_xSr_0.1)₂CuO_z with the T*-structure. This scattering in (La_0.9-xSm_xSr_0.1)₂CuO_z has the same features as that observed as the cylindrical-shape scattering in (Nd_0.8-xCe_xSr_0.2)₂CuO_z.
