摘要：
The invention provides a photoelectric conversion device, in which a decrease in sensitivity and a crosstalk between wirings are suppressed. Plural pixel columns are arranged in one direction, plural pixels are arranged in a different direction to the one direction in a column manner in the pixel column, and the pixel includes a photodiode PD, a reset transistor M4 for resetting the photodiode PD, and a source follower input transistor M3 for receiving a signal from the photodiode PD. An independent readout wiring 16 is individually provided for each pixel. The reset transistor M4 and the source follower input transistor M3 included in one pixel column or another pixel column are arranged between the photodiode column in one pixel column and the photodiode column in another pixel column arranged adjacent to the one pixel column.
