According to one embodiment, a photoelectric conversion device includes a first electrode, a second electrode, a photoelectric conversion layer provided between the first electrode and the second electrode, and a first layer provided between the second electrode and the photoelectric conversion layer, the first layer including a phenyl pyridine derivative. The phenyl pyridine derivative is represented by formula (1) below, Rings A, B, C, and D in the formula (1) are pyridine rings. Each of R1 to R11 in the formula (1) is one selected from the group consisting of hydrogen, a straight-chain alkyl group, a branched alkyl group, an aryl group, and an electron-withdrawing heteroaryl group.
