PURPOSE: A fluorescent lamp and a lighting apparatus are provided to prevent short circuit between a pair of lead wires by blocking continual adherence and deposition of electron emission matter on a stem between the pair of lead-in wires. CONSTITUTION: A fluorescent lamp comprises an arc tube bulb(1), a phosphor film(3) formed on the inner surface of the arc tube bulb, a discharge medium enclosed in the arc tube bulb, a pair of filaments(5) arranged within the arc tube bulb for generation of discharge, a pair of internal lead wires(4) to support the filaments, a stem(2) supporting the pair of internal lead wires(4) and with a pair of glass members(8) each protruding from one internal lead wire(4) to the direction of the other internal lead wire(4) and fixed to each internal lead wire(4) so as to overlap with each other but without contacting each other.
