  Attention is paid to the fact that the stress tensor diagonal components of
the point charged particle field in three-dimensional electrodynamics are equal
to zero. It allows to suppose the particle mass origin is field in the model,
if one loop correction to the classical potential of this field is taken into
account. In the noticed approach static potential and field strength are
evaluated and the electrical radius of the particle is found. It turns out that
this radius is connected with the vacuum polarization and with the particle
electrical field screening at the large distances.
