The opening portion has a first opening peripheral edge on one side in the thickness direction and a second opening peripheral edge on the other side in the thickness direction. In a projected view in the thickness direction, the second opening peripheral edge is disposed outside the first opening peripheral edge and extends along the first opening peripheral edge.
