The present invention provides a nitride semiconductor laser element,
comprising: a nitride semiconductor structure having a first nitride
semiconductor layer, a second nitride semiconductor layer, and an active
layer provided between the first and second nitride semiconductor layers;
a cavity end face provided to the nitride semiconductor structure; and a
protective film having a hexagonal crystal structure, and having a first
region provided on a first crystal surface of the nitride semiconductor
structure in the cavity end face and a second region provided on a second
crystal surface in the surface of at least one of the first and second
nitride semiconductor layer, the first and second regions of the
protective film are oriented in the same axial direction as that of the
respective first and second crystal surfaces.
