(110)-oriented γ-LiAlO2 film consisting of granular grains was prepared by laser CVD. The complex impedance of polycrystalline γ-LiAlO2 film showed dispersions due to bulk, grain-boundary and electrode. Temperature dependence of the electrical conductivity for γ-LiAlO2 film, polycrystalline sintered sample and single crystals obeyed Arrhenius behaviour. The electrical conductivity (σT) of the γ-LiAlO2 film reached 196 S∙m-1∙K at 1173 K, nearly 5 times higher than the maximum value of γ-LiAlO2 single crystals and polycrystalline sintered samples.
