Abstract
The occurrence of an upward streamer is effectively suppressed by reducing a positively charged region formed around a lightning protection device as much as possible. The lightning protection device includes: an inner electrode bodywhich is grounded; an outer electrode bodywhich is provided so as to enclose the inner electrode bodywith a predetermined gap G from the inner electrode body; an electrical insulator S which is provided in the gap G to hold the inner electrode bodyand the outer electrode bodyin a state of being electrically insulated from each other; and a support body for the inner electrode body, in which the inner electrode bodyis formed in a substantially spherical shape, the outer electrode bodyis formed in a spherical shell shape similar to an outer surface shape of the inner electrode body, and substantially an entire surface of the inner electrode bodyis covered by the outer electrode body
