A fluorescent lamp is manufactured according to the processes including: arranging a pair of lead wires between a holding block provided with two lead-wire grooves for grasping the pair of lead wires and an auxiliary holding block provided with grooves corresponding to the two-lead wire grooves in such a manner that both end portions of each of the pair of lead wires protrude out of the lead-wire grooves, whereby the pair of lead wires is supported to be sandwiched and to be fixed therebetween; attaching an electrode to tip ends of the protruding lead wires; inserting the lead wires that hold the electrode by grasping the same and protrude out of the holding block into an end portion of a glass tube; applying heat in the vicinity of the end portion of the glass tube so as to pinch-seal the lead wires; and detaching the holding block and the auxiliary holding block. Only the electrode is present between the lead wires, and therefore a simple, reliable and stable method for manufacturing a fluorescent lamp can be provided.
