A superficial diagram technique of the $1/N$ expansion is constructed for the twodimensional supersymmetric $CP^{N-1}$ model. A subtractional procedure is formulated together with a method for choosing a manifestly supersymmetric gauge. These determine UV- and IR-regular Green's functions of the physical fields in an arbitrary order in $1/N$.
