1. Apparatus for reducing charge for a vehicle, comprising:a body; and
a conductive wire that extends from the body, wherein
the body includes:
a radiation generating layer containing a natural ore containing a radioactive substance;
a first metal layer containing a metal with a redox potential of 0 V or less or an alloy of a metal with a redox potential of 0 V or less,; and
a second metal layer containing a metal with a volume electric resistance rate of 4.7 ??·cm or less at 0° C. or an alloy of a metal with a volume electric resistance rate of 5 ??·cm or less at 0° C., and
the conductive wire extends from the second metal layer and is electrically connective with at least one of a minus terminal of a battery provided in the vehicle and an electrically connective connection in the vehicle other than a plus terminal of the battery and a plus connection electrically connected with the plus terminal.
