A sealing layer () is formed over the first surface () of the substrate (), and seals the light-emitting unit (). In addition, the sealing layer () does not cover the first terminal () and the second terminal (). A cover layer () is formed over the sealing layer (), and is formed of a material different from that of the cover layer (). In at least a portion of a region located next to the first terminal () and a region located next to the second terminal (), a portion of an end of the cover layer () protrudes from the sealing layer ().
