摘要
A hollow cathode lamp (1), wherein a tubular member (8) is vertically installed on a stem (4) in a valve (2) to achieve an increase in productivity and a structure hard to produce the diffraction of discharge to an anode (7) from those other than a hollow cathode (10), whereby, the enclosure of the portion where the diffraction of discharge to the anode (7) is hard to occur can be achieved with such a simple structure that the tubular member (8) is installed vertically on the valve (2), the orderly arrangement of the hollow cathode (10) and the tubular member (8) using a tube axis (L) as the reference can be easily achieved by supporting a holder (11) on the end face (8c) of the tubular member (8) on a light outgoing window (3) side, and the holder (11) and hollow cathode (10) can be disposed concentrically to the tubular member (8) to increase the workability in assembly of the lamp (1).
