We present the results of a self-consistent spectroscopic analysis of theatmosphere of Ap-star HD 108662 based on high resolution spectrum and lowresolution spectrophotometric observations. Magnetic field effects, such asZeeman broadening and polarized line formation, were taking into account in theanalysis of spectral line profiles. We derived abundances of 24 chemicalelements as well as the stratification of Fe -- an element which is the maincontributor to the line absorption in the visible wavelengths. Another abundantchemical element -- Chromium -- was found to be distributed homogeneously inthe atmosphere of the star. From our analysis we determined the followingfundamental parameters of HD~108662: $T_{eff}$ = 10212 K, log$g$ = 4.0,$R/R_{\odot}$ = 2.09 and log$(L/L_{\odot})$ = 1.63. The estimated rotationalvelocity of the star is $v\,sini$ = 20.4 km/s and the strength of the surfacemagnetic field is $B_s$ = 3300 G.
