Abstract
A charge stripping method includes irradiating a charge stripping film with an ion beam. The charge stripping film includes a single layer body of a graphitic film having a carbon component of at least 96 at % and a thermal conductivity in a film surface direction at 25° C. of at least 800 W/mK, or a laminated body of the graphitic film. The charge stripping film has a thickness of not less than 100 nm and less than 10 μm, a tensile strength in a film surface direction of at least 5 MPa, a coefficient of thermal expansion in the film surface direction of not more than 1×10/K, and an area of at least 4 cm.
