Abstract Excited neutrinos nu* of the first generation are searched for in e^- p collisions at a centre of mass energy of 320 GeV. No evidence for nu* production is found in decay channels with a gamma or a weak boson decaying hadronically. Mass dependent exclusion limits on the ratio of coupling constants over compositeness scale are derived, covering also the high mass domain where the nu* would have a large intrinsic width.
