Claim:
1. A nitride semiconductor light emitting element comprising: a substrate; a buffer layer that is provided on the substrate; a foundation layer that is provided on the buffer layer; an n-type nitride semiconductor layer that is provided on the foundation layer; a light emitting layer that is provided on the n-type nitride semiconductor layer; and a p-type nitride semiconductor layer that is provided on the light emitting layer, wherein an X ray rocking curve half-value width ω (004) of a (004) plane that is a crystal plane of each of the layers of the nitride semiconductor light emitting element is 40 arc sec or less or an X ray rocking curve half-value width ω (102) of a (102) plane is 130 arc sec or less, and a ratio P (80)/P (25) between a light output P (25) at 25° C. and a light output P (80) at 80° C. with a same operating current is 95% or more.
