Abstract:
    The electric lamp has a lamp vessel (1) having an end portion (3) which is fixed inthe lamp cap (5) by means of polyethersulphone (8) as a thermoplastic synthetic resin, which has adhered both to the lamp vessel and to the lamp cap. The end portion has non-circular cross-sections where it is in contact with the synthetic resin (8) due to projections (10) projecting into the synthetic resin. A current supply wire (11) can be clamped between the synthetic resin and the sheath portion (6) of the lamp cap in order to establish electrical contact therewith. The lamp can be assembled by arranging in the hot state of the end portion a polyethersulphone ring (8) around this end portionand by providing the lamp cap in the hot state around the polyethersulphone ring.
