The electric incandescent lamp has a tubular quartz glass lamp vessel (1) in which a filament (10) having adjoining turns is axially disposed. The filament (10) is kept centered in the lamp vessel (1) by supports (15) which are connected to the filament (10) intermediate its ends (12) and which bear against the lamp vessel (1). The turns (11) of the filament (10) are formed as polygons, and the adjacent angles of adjoining turns are angularly displaced relative to one another about the axis (2) of the lamp vessel (1).
