  "textContent": "An apparatus includes pixels each including a conversion unit. The conversion unit includes a first semiconductor region of a first conductivity type, a second semiconductor region of a second conductivity type, and a third semiconductor region of the first conductivity type in order from a light incident surface side, and includes an in-pixel separation portion of the second conductivity type. The second semiconductor region includes a first end and a second end opposing the first end. The conversion unit further includes a fourth semiconductor region between the first and second ends. The in-pixel separation portion separates the first semiconductor region into a first region overlapping the first end and a second region overlapping the second end in a top view from the light incident surface side. A concentration of a second conductivity type impurity is lower in the fourth semiconductor region than in the in-pixel separation portion.",
