We present the structural parameters of ∼910 dwarf elliptical-like galaxies in the local universe (z <= 0.01) derived from the r-band images of the Sloan Digital Sky Survey (SDSS). We examine the dependence of structural parameters on the morphological types (dS0, dE, dE_bc, dSph, and dE_blue). There is a significant difference in the structural parameters among the five sub-types if we properly treat the light excess due to nucleation in dSph and dE galaxies. The mean surface brightness within the effective radius (<µ_e> ) of dSph galaxies is also clearly different from that of other sub-types. The frequency of disc features such as spiral arms depends on the morphology of dwarf galaxies. The most pronounced difference between dSph galaxies and other sub-types of early-type dwarf galaxies is the absence of disc feature which is thought to be closely related to their origin.
