1. A lens comprising:
a cover part; and
an interposing member formed of a light-reflecting material, wherein
the cover part comprises:
a lens part having a lateral side;
a connection part constituting a lateral side wall extending from the lateral side of the lens part; and
a flange part having a lower surface,
the interposing member has an upper surface and an inner lateral surface,
the upper surface of the interposing member abuts the lower surface of the flange part,
the lens part and the interposing member define a recess having an opening facing downward,
the lens part defines a bottom surface of the recess,
the inner lateral surface defines a lateral surface of the recess, which defines the opening of the recess,
the flange part extends outward from the opening of the recess,
the lens part has a convex lens, a light incidence surface, and a light-emitting surface with a plurality of projections,
the convex lens has a convex curved surface on each of the light incidence surface and the light-emitting surface,
the convex curved surface of the light incidence surface and the convex curved surface of the light-emitting surface overlapping in plan view,
when viewed in plan view, the plurality of projections are arranged in concentric circles or concentric ellipsoids surrounding the convex curved surface on the light-emitting surface,
at least a portion of the interposing member is located outside of the lens part in plan view, and
