The present invention provides a technique for fabricating a multicolor light-emitting lamp by using a blue LED having a structure capable of avoiding cumbersome bonding. In particular, the present invention provides a technique for fabricating a multicolor light-emitting lamp by using a hetero-junction type GaP-base LED capable of emitting high intensity green light in combination. Also, for example, in fabricating a multicolor light-emitting lamp from the blue LED and the yellow LED, the present invention provides a technique for fabricating a multicolor light-emitting lamp from a blue LED requiring no cumbersome bonding and a hetero-junction type GaAs.sub.1-ZP.sub.Z-base yellow LED of emitting light having high light emission intensity.
