We present the interpretation that the recently discovered Z(+)(4430) by the Belle Collaboration can be a radial excitation of the c (s) over bar state, being consistent with an observed value of the product of branching ratios, B(B-0 -> K(-/+)Z(+/-)(4430)) x B(Z(+/-)(4430) -> pi(+/-)Psi') similar to 10(-5). We give an explicit c (s) over bar candidate for this state by calculating the mass value in our semirelativistic quark potential model and also give a natural understanding for the facts that the decay mode Z -> J/Psi pi(+) has not yet been seen while Z -> Psi'pi can be seen.
