AN ION-GENERATING DEVICE (30) INCLUDES A DISCHARGE ELECTRODE (2) AND AN INDUCTION ELECTRODE (1). THE DISCHARGE ELECTRODE (2) HAS A NEEDLE-LIKE TIP. THE INDUCTION ELECTRODE (1) HAS A CIRCULAR THROUGH HOLE (1A). THE TIP OF THE DISCHARGE ELECTRODE (2) PENETRATES THE THROUGH HOLE (1A) OF THE INDUCTION ELECTRODE (1), AND PROTRUDES UPWARD WITH RESPECT TO AN UPPER SURFACE (1C) OF THE INDUCTION ELECTRODE (1). IT IS THEREBY POSSIBLE TO OBTAIN AN ION-GENERATING DEVICE CAPABLE OF IMPROVING ION EMISSION EFFICIENCY, AND AN ELECTRICAL APPARATUS PROVIDED WITH THE ION-GENERATING DEVICE.
