In this work, we present the study of superflares on solar-type stars using Transiting Exoplanet Survey Satellite ({\\em{TESS}}) data. 13 sectors of observations during the first year of the {\\em TESS} mission have covered the southern hemisphere of the sky, containing 25,734 solar-type stars. We verified 1,216 superflares on 400 solar-type stars through automatic search and visual inspection with 2-minute cadence data.
