We derive analytic expressions for the vector potential of electromagnetic wave radiated from a relativistic electron moving on a spiral orbit under an approximation that the velocity along the spiral orbit is much larger than that perpendicular to the axis. Based on this expression, we show that the electromagnetic wave has a spiral wave front and carries angular momentum.
