Claim Text:
1. A light emitting device comprising: a ceramic substrate including an upper surface with a rectangular shape, a lower surface with a rectangular shape, a first side surface, a second side surface opposed to the first side surface, a third side surface adjacent to the first and second side surfaces, and a fourth side surface opposed to the third side surface and being adjacent to the first and second side surfaces; a first lead located on a side of the first side surface of the ceramic substrate, the first lead including a first extending portion and a second extending portion; a second lead located on a side of the second side surface of the ceramic substrate, the second lead including a first extending portion and a second extending portion; a molded resin molded so as to integrate with the ceramic substrate, the first lead and the second lead, wherein the upper surface of the ceramic substrate includes an exposed region exposed from the molded resin and a covered region covered with the molded resin, and wherein the lower surface of the ceramic substrate is wholly exposed from the molded resin; and at least one light emitting element located on the exposed region of the upper surface of the ceramic substrate, wherein the covered region of the upper surface of the ceramic substrate is located adjacent to the first, second and third side surfaces, wherein the first extending portion of the first lead is located along the fourth side surface of the ceramic substrate so as not to be in direct contact with a first non-contact part of the fourth side surface adjacent to the first side surface of the ceramic substrate, and an end of the first extending portion of the first lead is in direct contact with a first contact part of the fourth side surface spaced apart from the first side surface by the first non-contact part, a gap between the first extending portion of the first lead and the first non-contact part being filled with a part of the molded resin, wherein the first extending portion of the second lead is located along the fourth side surface of the ceramic substrate so as not to be in direct contact with a second non-contact part of the fourth side surface adjacent to the second side surface of the ceramic substrate, and an end of the first extending portion of the second lead is in direct contact with a second contact part of the fourth side surface spaced apart from the second side surface by the second non-contact part, a gap between the first extending portion of the second lead and the second non-contact part being filled with a part of the molded resin, and wherein the end of the first extending portion of the first lead and the end of the first extending portion of the second lead are exposed from the molded resin in a top view.
