A solid state image sensor is constructed such that a plurality of linear image sensors are provided to have at least one row of photodiodes in each of the plurality of linear image sensors and a photodiode array is formed by arranging the plurality of linear image sensors side by side. A control gate electrode used to retrieve electric charges and a polysilicon electrode serving as a charge transfer electrode are provided between the pluraliielding conductive film is provided on the polysilicon electrode to partition the plurality of linear image sensors into individual linear image sensors. Accordingly, a light beam incident on a certain linear image sensor can be prevented from entering another linear image sensor adjacent to the certain linear image sensor, thereby reducing a difference between the amounts of signal charges outputted from different linear image sensors and suppressing smear.
