A slip control device for an electric automobile includes a maximum rotation frequency calculator to calculate 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 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 is made to be zero.
