Resumen:
   We compute the exact induced parity-breaking part of the effective action for 2+1 massivefermions in QED_3 at finite temperature by calculating the fermion determinant in a particularbackground. The result confirms that gauge invariance of the effective action is respected even when large gauge transformations are considered.
