Stark broadening parameters, widths, and shifts for 33 Cd I singlets and 37 triplets were calculated using the semiclassical perturbation method. The results were compared with available experimental and theoretical data. Also, regularity in the spectral series 5s² ^1S-np ^1P° was investigated. The influence of Stark broadening was analyzed in A-type stellar atmospheres.
