PROBLEM TO BE SOLVED: To provide a solid state image pickup device having a high performance which can reduce a step difference by electrodes and can minimize it. SOLUTION: This device is provided with a channel layer 4 formed in a belt shape at a surface part in a semiconductor substrate 1, a photodiode part 16 formed in the substrate 1 and adjoining the channel layer 4, an insulating film 2 formed on the substrate 1, first electrodes 13 and 15 so formed on the insulating film 2 as being insulated from each other at the rectangular direction of the channel layer 4 and as adjoining each other and a wiring layer which junctions the diode part 16 with the electrodes 12∼15. Parts of the electrodes 12∼15 on the photodiode part 16 are eliminated. In this case the first electrodes 13 and 15 and the second ones 12 and 14 on the channel layer 4 are so comprised as being duplicated in a part and upper surfaces of the electrodes 13 and 15 and ones of the electrodes 12 and 14 being made to be a common plane and a part of the first electrodes 13 and 15 of the wiring layer and a part of the second electrodes 12 and 14 are so comprised as being perfectly duplicated.
