1. A light-emitting device comprising: a package including a concave portion which has a bottom surface, an opening on a front side opposite to the bottom surface in a front direction vertical to the bottom surface, and an inner peripheral wall connecting the bottom surface and the front side, the bottom surface comprising: at least one light-emitting element arranged on the bottom surface of the concave portion and having a polygonal shape viewed along the front direction, each interior angle of the polygonal shape being less than 180 degrees, the polygonal shape having light-emitting element distances between vertexes of the polygonal shape and having a longest light-emitting element distance among the light-emitting element distances, the at least one light-emitting element being arranged such that a light-emitting element lateral line along the longest light-emitting element distance is substantially parallel to a package lateral line along the longest package distance and such that a first outer peripheral portion of the at least one light-emitting element which is closest to the upper side of the concave portion is shorter than a length of a side, of which inclination to the package lateral line is minimum, out of sides of the at least one light-emitting element on a lower-side side of the concave portion viewed along the front direction.
