Abstract
The present invention is directed to a photoconductive switch module. The photoconductive switch module comprises a first substrate having light-emitting elements, 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/distinction 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. Drive light emitted from a light-emitting element is trapped within a through hole to travel to a photoconductive switch element. The first substrate and the third substrate are connected to each other by heating and pressure contacting of first metal members.
