We obtained narrow-band continuum images of the Crab Nebula at 16, 6.4 and 2.2 µm. From these we derive spectral index maps, extending the optical work of Véron-Cetty & Woltjer (1993). In the central parts of the Nebula the IR spectral index is close to the radio one, indicating the region where the radio-emitting electrons are accelerated.
