PROBLEM TO BE SOLVED: To provide an inexpensive halogen lamp while utilizing characteristics of tungsten with rhenium. SOLUTION: A tungsten filament 12 having a light emitting part 121 and a non-light emitting part 122 locally in the longitudinal direction and inert gas are sealed in a quartz glass bulb 11 having sealing parts 131, 132 at both ends, and external lead-in wires 151, 152 connected to the filament 12 are lead out of the sealing parts 131, 132 to structure the halogen lamp L1. A rhenium tungsten filament 22 having a light emitting part 221 and a non-light emitting part 222 locally in a longitudinal direction and inert gas are sealed in a quartz glass bulb 21 having sealing parts 231, 232 at both ends, and external lead-in wires 251, 252 connected to the filament 22 is lead out of the sealing parts 231, 232 to structure the halogen lamp L2. By emitting light from the halogen lamp L2 in a stand-by state, power consumption can be reduced. COPYRIGHT: (C)2011,JPO&INPIT
