小なることを特徴とするハロゲン電球。 A tube, a pair of metal foils embedded in a sealed portion of the tube, a pair of external lead rods extending outside the tube from each of the pair of metal foils, and a pair of external lead rods extending into the tube from each of the pair of metal foils. and a double coil filament stretched between the tips of the pair of internal lead rods, the double coil filament having two single coil filament parts extending from both ends, and the single coil filament having two single coil filament parts extending from both ends. In the halogen light bulb configured such that the coil filament portions are locked by being held between the bent tips of the pair of internal lead rods, the winding pitch of the single coil filament portion is the same as that of the double coil filament portion. A halogen light bulb characterized in that the pitch of the primary winding is smaller than that of a halogen light bulb.
