Abstract: We investigate the possibility of detecting the astrometric microlensing of QSOs caused by Galactic stars and MACHOs using VERA (VLBI Exploration of Radio Astrometry). First we briefly introduce the VERA project, a ground-based radio astrometric mission which aims at astrometric accuracy at the 10 micro arcsecond level. In the second part of this paper, we present model calculations of the optical depth and event duration of astrometric microlensing caused by Galactic stars and MACHOs, and we discuss the implications for VERA.
