Abstract
A photoelectric conversion device includes a connecting portion that electrically connects a contact plug of anode wiring and the second semiconductor region of the isolation portion. The connecting portion includes a third semiconductor region of the second conducting type that is connected to the contact plug of the anode wiring, and a fourth semiconductor region of the second conducting type that is disposed between the third semiconductor region and the second semiconductor region. The impurity concentration of the third semiconductor region is higher than the impurity concentration of the second semiconductor region and the impurity concentration of the fourth semiconductor region is lower than the impurity concentration of the third semiconductor region. With respect to a direction in which the APDs are arrayed, the width of the isolation portion is smaller than the width of the connecting portion.
