摘要：A photoconductive antenna includes a semiconductor layer, and first andsecond electrodes. The semiconductor layer includes a first conductive region and a

second conductive region constituting portions of a surface of the semiconductor layerdisposed on a side to which the pulsed light is irradiated, and a third conductive regiondisposed between the first and second conductive regions. The first conductive regioncontains a first conductive type impurity and the second conductive region contains asecond conductive type impurity. The third conductive region has a carrier density lowerthan a carrier density of the first conductive region or a carrier density of the secondconductive region. The first electrode and the second electrode are disposed on the sideto which the pulsed light is irradiated. The third conductive region is configured andarranged to be irradiated by the pulsed light.
