'''Abstract''':
a lightning protection device for protecting a dc power supply device from a lightning surge current includes: a positive-electrode-side lightning arrester connected between a positive-electrode-side power cable of the dc power supply device and a ground point; and a negative-electrode-side lightning arrester connected between a negative-electrode-side power cable of the dc power supply device and the ground point, in which a difference in operating voltage between the positive-electrode-side lightning arrester and the negative-electrode-side lightning arrester is equal to or more than a reference value.
