The present invention relates to an anisotropic complex sintered magnet including MnBi with magnetic characteristics enhanced and an atmospheric sintering method for preparing the same. The anisotropic complex sintered magnet including MnBi according to the present invention may implement excellent magnetic characteristics, and thus may replace rare earth bond magnets in the related art, and a continuous process is enabled because the magnet is prepared by an atmospheric sintering method, and a sintering method used in the permanent magnet process in the related art is used as it is, so that the anisotropic complex sintered magnet is economical.
