The invention discloses a photoelectric converting device and an image collecting device. In the photoelectric converting device, multiple groups of unit pixels are configured in a trap; each unit pixel comprises a photoelectric converting element, an amplifier transistor and a transmission transistor. The photoelectric converting device comprises a wire supply voltage to the trap, a trap contactpart for connecting the voltage supply wire to the trap and a transmission control wire controlling the transmission transistor. In each region of the unit pixel group, the transmission control wire is configured symmetrically relative to the trap voltage supply wire.
