An electron generating means for generating electrons in a stable state in which a circuit is not easily damaged. To provide a combustion promoting means, a moving body, and a sterilizing / deodorizing means including the electron generating means. In an electron generating means for generating electrons, a current is applied only in a state where a first terminal of a rectifier circuit is at a negative potential by a rectifier circuit before flowing AC power from a power source to the booster circuit. In the booster circuit, electrons are generated only from one terminal on the secondary side. In the combustion promoting means, the electrons are supplied to the internal combustion engine, and the fuel particles are attracted to the surrounding metal portion forming the fuel combustion space by electrostatic attraction to promote vaporization.
