Abstract
A method of manufacturing a film type light receiving element in which the electric current ratio for light and dark input intensities is maximized. Metal electrodes and a photoconductive film are provided in the form of belt-shaped layers on a flat smooth substrate such as a quartz layer. An optically transmissive electrode film of a tin oxide compound is formed thereon in a magnetron type sputtering device. Utilizing the fact that the electric current ratio for light and dark input intensities of the light receiving element varies according to the oxygen partial pressure of the sputtering atmosphere in the sputtering device, the oxygen partial pressure is set close to a value at which the electric current ratio for light and dark input intensities is at a peak value.
