Abstract With the help of a postulate of gauge group parameter involved with ghost fields, the infinitesimal gauge transformation laws preserving the gauge-invariance of the quantum Lagrangian itself of the quantized Glashow--Weinberg--Salam model are established precisely. The corresponding Ward--Takahashi identity for the model is derived exactly.
