We analyze the divergent part of the one-loop effective action for the
noncommutative SU(2) gauge theory coupled to the fermions in the fundamental
representation. We show that the divergencies in the 2-point and the 3-point
functions in the $\theta$-linear order can be renormalized, while the
divergence in the 4-point fermionic function cannot.
