  We construct a coherent state path integral formalism for the one-dimensional
Bloch particle within the single band model. The transition amplitude between
two coherent states is a sum of transition amplitudes with different winding
numbers on the two-dimensional phase space which has the same topology as that
of the cylinder. Appearance of the winding number is due to the periodicity of
the quasi-momentum of the Bloch particle. Our formalism is successfully applied
to a semiclassical motion of the Bloch particle under a uniform electric field.
The wave packet exhibits not only the Bloch oscillation but also a similar
breathing to the one for the squeezed state of a harmonic oscillator.
