Abstract
A light emitting diode 21 in which a through hole 25 is provided in a glass epoxy substrate 22 which extends from the upper surface 26a to the lower surface 26b thereof, a transparent resin section 27 is used to fill the through hole 25, a light emitting diode element 29 made of a gallium nitride based compound semiconductor with a transparent element substrate of sapphire glass 30 is fixed on top of the transparent resin section 27 using a transparent adhesive 37, and light blocking electrodes 33, 34 are provided on the upper surface of the light emitting diode element 29, and light emitted from the light emitting diode element 29 passes through the transparent resin section 27 and is guided out through a bottom surface 26b of the glass epoxy substrate 22. When the light emitting diode 21 is mounted onto a motherboard 41, by dropping the resin sealing body 38 of the light emitting diode 21 down into an insertion hole 42 formed in the motherboard 41, the height dimension of the mounted light emitting diode 21 mounted can be reduced.
