PROBLEM TO BE SOLVED: To allow light emission of a filament to be disturbed a little by a lead wire, and shading action by the lead wire toward main light emission of the filament to be lightened. SOLUTION: The incandescent lamp is provided with glass bulb 1 almost symmetrical with its axis, a first coil filament 4 to the axial direction in the glass ball 1, a second coil filament 5 to a lateral direction in the glass ball 1, and an anchor for holding both the filaments 4, 5 and performing electric connection. This anchor includes a shading device 6 for a first coil filament 4, and 3 lead wires 7, 8, 9. The 3 lead wires 7, 8, 9 are arranged within one common plate vertically to a longitudinal axis of the second coil filament 5. At least one lead wire 8 includes a portion 8a projecting from the common plate and leading to pass near the second coil filament. This portion 8a is formed to arrange in an outside of the main light emission direction of the second coil filament 5. |
