  We prove the dispersive and Strichartz estimates for solutions to the wave
equation with a class of many-electric potentials in spatial dimension three.
To obtain the desired dispersive estimate, based on the spectral properties of
the Schr\"odinger operator involved, we subsequently prove the dispersive
estimate for the corresponding Schr\"odinger semigroup, obtain a Gaussian type
upper bound, establish Bernstein type inequalities, and finally pass to the
M\"uller-Seeger's subordination formula. The desired Strichartz estimates
follow by the established dispersive estimate and the standard argument of
Keel-Tao.
