The present invention is to provide apparatus for reducing charge for vehicle that is capable to decrease the charge taken by a vehicle regardless of the type of the drive source, which is more reasonable without relying on external energy supplied from, for example, a battery carried in a vehicle and which enables its small size. The apparatus for reducing charge for vehicle 1 of the present invention includes a body 10 and a conductive wire 20 that extends from this body 10. The body 10 includes a radiation generating layer 11 containing a natural ore containing a radioactive substance, a first metal layer 12 containing a metal with a redox potential of 0 V or less or an alloy of this metal, and a second metal layer 13 containing a metal with a volume electric resistance rate of 4.7 μΩ·cm or less at 0° C. or an alloy of this metal. The conductive wire 20 extends from the second metal layer 13 and is connected with at least one of predetermined electrically connective connections in a vehicle including a minus terminal of a battery provided in the vehicle.
