<p>A reflective light emitting diode (LED) 1 has a pair of leads 3a, 3b for supplying an electric power to an LED element 2. The LED element is mounted on a lower surface of one 3a of the leads. A wire 4 bonds the other lead 3b and the LED element 2 to connect them electrically. An aluminum plate is pressed to form a reflection mirror 5 of concave shape. The reflection mirror 5 is attached to the leads 3a, 3b. An encapsulating resin 6 encapsulates the leads 3a, 3b and the reflection mirror 5. At the same time, a flat shape of a radiation portion 7 is molded at a back of the LED element 2. The lead 3a on which the LED element 2 is mounted is disposed near a flat marginal portion 5a of the reflection mirror 5 with an insulating sheet material 8 having a ring shape of 0.1mm thick.</p> |
