摘要：
A dielectric device of higher performance is provided. An electron emitter, to which the dielectric device is applied is provided with: an emitter including a dielectric; and an upper electrode and a lower electrode to which drive voltage is applied in order to emit electrons. The emitter is formed by the aerosol deposition method or the sol impregnation method.
