入したことを特徴とする白熱電球。 A glass tube that has a tip-off part at one end and a pinch seal part at the other end, and has an infrared reflective film formed on its surface, two long and short internal lead-in wires extending into this glass tube, and these internal lead-in wires. metal foils connected to the metal foils and buried in the pinch seal part, external lead-in wires connected to these metal foils and led out from the pinch seal part, and connections between the two long and short internal lead-in wires. In the incandescent light bulb, the double coil filament is arranged such that its central axis coincides with the central axis of the glass tube. By caulking the tip of the shorter internal lead-in wire of the two long and short inner lead-in wires, the double coil filament is attached to the tip of the shorter inner lead-in wire. One single coil part is fixed, and the longer internal lead-in wire is folded back to form a folded part, and the other single coil part of the double coil filament is inserted inside this folded part, and the other single coil part is folded back. An incandescent light bulb characterized in that the other single coil part is fixed to the folded part by caulking the folded part, and a tip of an extension part obtained by extending the folded part is inserted into the tip-off part.
