PROBLEM TO BE SOLVED: To provide a simple illumination lamp which, when assembling a heat sink and a globe, does not require an adhesive agent even when connection structures of these are small components with each other, and which does not require complicated connection structures, either.SOLUTION: An illumination lamp 10 includes: a heat sink 20 in which one end of a cylinder for accommodating a light emitting substrate 40 mounting a light emitting element 41 is open; and a translucent globe 30 for covering the opening of the heat sink 20. The illumination lamp has: screwing parts 22, 32 which screw peripheral surfaces with each other formed at opening end parts 23, 31 where the heat sink 20 and the globe 30 are overlapped, and in which one is made to be a male screw 22a and the other is made to be a female thread 32a; a fitting part 70 which is provided in a circumferential direction of an end surface 23a of the opening end part 23 of the heat sink 20; and an engagement part 34 which is protrusively provided at an opening end surface 33 of the globe 30 and which elastically deforms while sliding with the end surface 23a of the heat sink 20. |
