A Light-emitting diode which comprises a pair of metal plate leads
connected to a light-emitting element. The pair of metal plate leads
comprise, at the edges of the metal plates, surface mounting-type
connecting parts that connect facing the pads of a circuit substrate.
Furthermore, the light-emitting diode comprises a support member that has
a part, other than leads, that contacts the circuit substrate so that it
can be positioned on the circuit substrate with stability during the
reflow process.
