To provide an electrified charge reduction apparatus for a vehicle which achieves further miniaturization or high density.SOLUTION: A radiation irradiation structure (substance activation member 10) is a laminated structure of a metal layer 11 and a radiation generation layer 12. The metal layer 11 includes metal having an oxidation reduction potential of 0 V or less and has a plate shape or a foil shape. The radiation generation layer 12 contains a mixture of natural ore containing a radiation substance, conductive metal powder, and a radiation transmissive resin. The conductive metal powder is metal powder or alloy powder having volume electric resistivity at 0°C of 5 μΩ cm or less, and a radiation dose generated by the radiation generation layer 12 is 0.02 μSv/h or more and 0.2 μSv/h or less.SELECTED DRAWING: Figure 1
