Spectra of sunspots in the regions of the Li I 6708 Å line and certain Fe I and Ca I lines are presented. The observations wee carried out in August 2014 using a CCD array mounted at the BST-2 telescope of the Crimean Astrophysical Observatory. Sunspot models based on the observed Fe I and Ca I line profiles have been computed, and used together with the observed Li I 6708 Å profiles to determine the lithium abundances. The mean lithium abundance for the sunspots observed on August 26, 2014 is logA(Li) = 1.2 (on a scale for which logA(H) = 12.0). Sunspot spectra obtained on October 8, 2011 were also analyzed, yielding logA(Li) = 1.02.
