The electrical and thermal conduction properties of a material can be similar or very different, in metals the electrical and thermal conductivity is due to free electrons, in non-metals thermal conductivity has nothing to do with free electrons, but more to do with lattice vibrations (that is, phonons).
So mica has good thermal conductivity due to phonons, but doesn't have sufficient free electrons and a very high resistance to be a good conductor of electricity.
Hence, Mica is a poor or bad conductor of electricity.
