ABSTRACT:
An incandescent lamp includes a bulb formed of a light-transmissible material, a stem portion for supporting lead-in wires having a filament, and a connector positioned between the bulb and the stem portion to connect them in a hermetically sealed fashion at opposite ends thereof. Since the stem portion is preformed after which the stem is connected integral with the bulb by the connector, it is possible to position the filament as a light source with high accuracy.
