抄録	The heating process is a useful method to change TiO₂ film property. When using a continuous wave (CW) fiber laser, local heating can be performed. In our experiments, the film was formed by aerosol beam irradiation. The films were irradiated with a CW fiber laser in vacuum and in air. The film was darkened after the CW fiber laser irradiation in vacuum. The electric resistance of the darkened area on the films was decreased as the energy per unit area was increased. However, the film was not changed after the CW fiber laser irradiation in air. In our previous study, the films were darkened by femtosecond laser irradiation in air. Then, electrical resistance of the darkened area on the films also decreased. Electric resistance of the darkened area after CW fiber laser irradiation in vacuum was much smaller than that after femtosecond laser irradiation.
