Using the radio flux and angular size of the radio core of the M87 jet measured by VLBA at 43~GHz, we estimate the  energy densities of magnetic field and relativistic electrons in the core at 43~GHz  by the comparison with one-zone synchrotron self absorption (SSA) model to the observed  core. In this talk, we especially discuss (i) angular size dependence of these densities, and (ii) consistencies of derived densities with observed SED.
