  We show that Bogoliubov's quasiparticle in superfluid $^3He-B$ undergoes the
Zitterbewegung, as a free relativistic Dirac's electron does. The expectation
value of position, as well as spin, of the quasiparticle is obtained and
compared with that of the Dirac's electron. In particular, the Zitterbewegung
of Bogoliubov's quasiparticle has a frequency approximately $10^5$ lower than
that of an electron, rendering a more promising experimental observation.
