In this LED lamp, the inside of an external enclosure comprising a globe (30) and a case (50) is segmented into a globe-side space and a case-side space by a base (20) that closes an opening at the end of the globe (30). An LED (12) is stored in the globe-side space, and a circuit unit for lighting said LED (12) is stored in the case-side space. The LED (12) is thermally connected to the base (20), and the base (20) and the case (50) are joined to the globe (30) in a manner such that more heat is transferred from the base (20) to the globe (30) than from the base (20) to the case (50).
