Spectroscopic observations of the DQ Her-type Nova V705 Cas in the wavelength range H_gamma - 7400 A at the nebular stage are presented. The Balmer decrement yields E_(B-V) = 0.98. Based on statistical relationships, we estimated E_(B-V) to be 0.7 and the distance to the Nova to be 1.17 kpc. The discrepancy between the estimates of E_(B-V) may result from circumstellar reddening after the formation of a dust shell. The helium, oxygen, nitrogen, argon, iron, and calcium abundances in the Nova shell are determined. The shell of V705 Cas is similar in chemical composition to those of other DQ Her-type novae.
