Thermal conductivity 
under a field is investigated
in 
-wave superconductors and isotropic s-wave
superconductors by the linear response theory, using a microscopic
wave function of the vortex lattice states.
To study the origin of the different field dependence of
between higher and lower temperature regions,
we analyze the spatially-resolved thermal conductivity around a vortex
at each temperature, which is related to the spectrum of the local density
of states.
We also discuss the electric conductivity in the same formulation
for a comparison.
