The Crab pulsar emission can be described adequately by using the phase-averged spectrum, which is continuous from the near infrared to the gamma-ray range. Using most of the published observations over this energy range, a power law fit to the emission requires at least two power laws with a break of 0.74 + or - 0.02 in spectral index at 39 + or - 3 keV. If this emission is synchrotron radiation, then the emitting electron spectrum is continuous over about five decades and has a break of about 1.5 in spectral index at gamma = E/(m c sq). With B(perpendicular) = 1 MG, the electrons emitting in the infrared have gamma = 10. Because a fit with three power laws has approximately the same chi squared, a gradual turnover is consistent with the data, as would be expected from synchrotron emission.
