The divergence of the photon self - energy diagram in spinor quantumelectrodynamics in $(2+1)$ dimensional space time- $(QED_3)$ is studied by thePauli - Villars regularization and dimensional regularization. Results obtainedby two different methods are coincided if the gauge invariant of theory isconsidered carefully step by step in these calculations.
