An LED housing, in which a heat conducting part has a chip mounting area, a heat connecting area opposed to the chip mounting area and a neck between them. Fixing parts have first ends engaged with the neck. An electrical connecting part has a wire connecting area placed adjacent to the chip mounting area and an external power connecting area connected to the wire connecting area. A housing body of molding material integrally holds the heat conducting part, the fixing parts and the electrical connecting part while isolating the electrical connecting part from the heat conducting part. The LED housing fixes the neck of the heat conducting part at both sides, thereby stably coupling the heat conducting part to the housing body. The fixing parts can spread heat from the heat conducting part to lateral regions of the LED housing, thereby more efficiently spreading heat.
