A pickup device according to the present invention includes a photoelectric conversion portion, a charge holding portion configured to include a first semiconductor region, and a transfer portion configured to include a transfer gate electrode that controls a potential between the charge holding portion and a sense node. A second semiconductor region is disposed on a surface of a semiconductor region between the control electrode and the transfer gate electrode. A third semiconductor region is disposed below the second semiconductor region. An impurity concentration of the third semiconductor region is higher than the impurity concentration of the first semiconductor region.
