A slip control device for an electric automobile which assuredly eliminates a slippage with a simple configuration without involving a wasted decrease in running performance, is provided. A maximum rotation frequency calculator 22 calculates a drive wheel maximum rotation frequency Nmax on the basis of a rotation frequency N1 of a driven wheel and an ideal slip ratio λmin according to the following formula, (Nmax−N1)/N1=λmin. It is determined whether a drive wheel rotation frequency N2 exceeds the frequency Nmax. If it is determined that the frequency N2 exceeds the frequency Nmax, a torque command value to a motor unit 3 is made to be zero.
