摘要： The present invention is directed to a photoconductive switch module. The photoconductive switch module comprises a first substrate having light-emitting elements, and a second substrate having photoconductive switch elements, whose number is equal to that of the light-emitting elements. The light-emitting elements face the photoconductive switch elements, so that the photoconductive switch elements are turned on/off in accordance with lighting/extinction of the light-emitting elements. The photoconductive switch module further comprises a third substrate arranged between the first substrate and the second substrate. The third substrate has through holes, whose number is equal to that of the light-emitting elements. Each through hole is positioned between a light-emitting element and a photoconductive switch element facing each other. Drive light emitted from each light-emitting element travels to the photoconductive switch element via the through hole.
