We present a new catalog of dwarf galaxies in the Virgo cluster using SDSS DR7 data. Basically, morphologies of galaxies are classified based on the image and spectral feature of SDSS data. We secure 994 dwarf galaxies as members of the Virgo cluster, from which 492 galaxies are new objects not included in the previous catalog. By matching with GALEX GR5 data, we present ultraviolet properties of various dwarf galaxies in the Virgo cluster. We suggest that there are different star formation histories among different subclasses of early-type dwarf galaxies in the Virgo cluster related with their morphology and environment.
