The Solar-B mission includes an Extreme-UV Imaging Spectrometer (EIS). This instrument detects photons in the wavelength ranges 170 - 210 Å and 250 - 290 Å which include emission lines from several highly ionised species that exist over the temperature range of 4.7 to 7.3 in Log T. In this summary paper, we will describe the design and operation of the instrument, present its performance parameters e.g. spectral and spatial resolution and sensitivity, and summarize its calibration. Its role in the Solar-B mission will be illustrated with reference to some key science topics. The anticipated observing strategy for the first three months of the mission will be outlined.
