A unit vector is a vector whose magnitude is always unity that means 1. It gives the direction of that quantity which is represented by this vector.

If the electric field is represented by a unit vector so it has same unit as electric field that means Newton per coulomb.

The unit of unit vector depend on the quantity for which it is used.
