Stark widths of 117 Ne II spectral lines have been measured. For 86 of the lines these are the first measures to the authors' knowledge. A pulsed arc was used as a plasma source. The electron density, determined both interferometrically and spectroscopically, covers the range (2.5-7.5)×1022 m-3. The electron temperature, determined from Boltzmann plots, covers the range of 25,000-45,000 K. Possible dependencies of the Stark width on the temperature have been checked. In some cases the Stark widths obtained in this work disagree with the Griem theoretical results and the experimental data available in the literature.
