PURPOSE:To obtain an LED whose takeout efficiency is good by using a reflection member which has been resin-molded to a lead frame which has omitted a drawing working operation and whose shape is simple by a method wherein a nearly conical reflection face which reflects light radiated from a light-emitting chip forward and a long hole which has been opened on the opposite side from the bottom continued to the reflection face are molded in the reflection member and the light-emitting chip and one part of the reflection member are sealed with a resin. CONSTITUTION:A reflection member 21 is provided with a long hole 22 which is fitted to the width and the thickness of tip parts 12, 17 of lead members 11, 16; reflection faces 23 which have been inclined to the outside from its circumference are formed at one end part of the long hole 22. Abutment faces 24, 25 on stepped parts 14, 19 of the lead members 11, 16 are formed at the other end part of the long hole 22. The tip parts 12, 17 of the lead members 11, 16 are inserted into the long hole 22 of the reflection member 21 which has been molded in this manner; a light-emitting chip 28 is bonded to flat parts 13, 18 of the lead members 11, 16; after that, a lens member 29 is molded out of a transparent resin such as an epoxy resin or the like so as to surround the whole circumference of the reflection member 21; an LED 20 is formed. |
