In a power supply device of the invention, when the state of charge SOCof a low-voltage battery is lower than a discharging reference value Shibelow a full charge level and when the state of charge SOCof a high-voltage battery is not lower than a discharging reference value Slowat a system-off time, the low-voltage battery is charged close to its full charge level with the electric power supplied from the high-voltage battery. The lead acid battery used for the low-voltage battery has the high potential for deterioration in the continuously low state of charge SOC. The lithium secondary battery used for the high-voltage battery has the high potential for deterioration in the continuously high state of charge SOC. The charge of the low-voltage battery in combination with the discharge of the high-voltage battery enables both the low-voltage battery and the high-voltage battery to have respective favorable states of charge with little potentials for deterioration. The technique of the invention thus effectively prevents quick deterioration of both the low-voltage battery and the high-voltage battery.

A non-linear optical silica thin film ( ) whose main material is SiO &mdash;GeO is formed by irradiating positive or negative polar particles and polarization orientation is carried out in the silica thin film. For example, by repeating, while forming the silica thin film ( ), forming the thin film in a state of irradiating positive particles, forming the thin film in a neutral state, such as irradiation of neutral particles or non-irradiation of particles, forming the thin film in a state of irradiating negative particles, and forming the thin film in a neutral state, a plurality of regions ( - - and - ) in different states of polarization orientation are formed in a direction of film thickness of the silica thin film ( ). Distribution of charges arises in the silica thin film ( ) being formed by irradiation of polar particles and polarization orientation is automatically carried out in the silica thin film ( ). Thus, without carrying out an post process of polarization orientation, such as application of voltage, a polarization orientation process is completed almost simultaneously with completion of forming the silica thin film ( ). Thus, it is possible to form periodical polarization orientation structure in a direction of film thickness.
