Abstract

A photodetector 1 comprises: a vacuum housing 2 having a window part 12; a photoelectric surface (first photoelectric conversion layer) 3 configured to emit electrons E in accordance with incidence of light L1; a phosphor layer (second photoelectric conversion layer) 4 configured to generate light L2 in accordance with incidence of the electrons E emitted from the photoelectric surface 3; and a semiconductor photodetection element 5 arranged on an opposite side of the photoelectric surface 3 so that the phosphor layer 4 is sandwiched therebetween and configured to detect the light L2 generated from the phosphor layer 4. The semiconductor photodetection element 5 is arranged to be separated from the phosphor layer 4.
