A light emitting device includes a semiconductor package, and a mounting board having first and second wiring components respectively connected to first and second conduction members of the semiconductor package. The semiconductor package includes: a light emitting element; a first conduction member, on one side of which the light emitting element is placed; and a second conduction member whose surface area is smaller than that of the first conduction member, the other side of the first and second conduction members, forms the lower face of the semiconductor package. The mounting board includes: a narrow part and a wide part wider than the narrow part, which are formed on the first and second wiring components. At least the narrow part is joined to the first and second conduction members, and the first wiring component has a recess in its interior. |
