ABSTRACT:
The present invention provides a sub-mount type device for emitting light which has high speed response and yet can radiate heat sufficiently. The sub-mount type device for emitting light comprises a heat sink (4), a sub-mount body (62) mounted on the heat sink (4) which comprises an insulating layer (38) with a upper face and a lower face, a upper electrode (42) on the upper face and a lower electrode 44 and 36 on the lower face, the insulating layer having two parts of the insulating layer (38) thickness of which is different, and a chip (30) for emitting light above the thinner part (39) of the insulating layer (38).
