An electric heating device (1) for a fluid comprises a heating chamber (5), which is enclosed by an approximately cylindrical wall (6) and into which the fluid enters through a supply connector (7) and out of which the fluid exits through a discharge connector (8). In the heating chamber is a heating body (10) comprising a jacket tube (11), in the interior of which tube a heating-wire spiral (12) extends, the two ends of which spiral can be connected to a source for electrical heating energy, wherein the jacket tube comprises a helical helix portion (20) which is arranged such that its longitudinal axis (19) coincides with the central axis of the cylindrical wall of the heating chamber. In order to achieve effective flow through all volume portions of the heating chamber and optimal heat transfer from the heating body to the fluid, a bead is formed in the cylindrical wall of the heating chamber, which bead extends in the axial direction, is helical and is concave with respect to the interior of the heating chamber, and which bead has the same pitch and the same turn direction as the directly adjacent helix portion of the jacket tube.
