  We calculate the specific heat of the inner crust of neutron stars within a
local-density approximation to an improved relativistic Hartree-Bogoliubov
theory. Non-uniformness of the system enhances the specific heat in particular
at low temperatures. The degree of enhancement is similar to that in the
spherical phase of Elgar{\o}y et al. We examine a schematic interpolation
between the results of Broglia et al. adopting the Gogny force and ours based
on the Lagrangian of the relativistic mean field model.
