A surface-emitting light source includes: a wiring substrate including a wiring layer on a base member; a light-guiding plate having a first primary surface and a second primary surface facing the wiring substrate; a light-reflective resin portion having an opening and being disposed between the light-guiding plate and the wiring substrate; and a light source portion including an element electrode on a first surface thereof and a light-extracting surface on a second surface thereof that faces the light-guiding place. The element electrode is electrically connected to the wiring layer via the opening, which is equal to or smaller than an area in which a side surface of the light source portion contacts the resin portion. The resin portion and the light-guiding plate face each other and are bonded to each other, and the resin portion and the wiring substrate face each other and are bonded to each other.
