PURPOSE:To obtain a sufficiently big photocurrent in a simple composition by connecting electrically both these electrodes after connecting electrodes on both an upper part and a lower part of a photoelectric converter. CONSTITUTION:After an Al layer 102 is formed all over a glass substrate 101, lower electrodes 103 and 104 are formed from the layer 102 with a photolithography method. A photoconductive layer 105 is formed over the electrodes 103 and 104. An N<+> layer 106 is formed on the layer 105. An Al layer 107 is formed all over the substrate 101. The upper electrodes 108 and 109 are formed from the layer 107. A light emitting portion 110 is formed after eliminating the layer 106 by using the electrodes 108 and 109 as masks. The photosensor connecting the layer 105 with both the upper and the lower electrodes can get a sufficiently big photocurrent in a simple composition. |
