We discuss the effect of local type non-Gaussianity on the abundance of primordial black holes based on the peak theory. It is explicitly shown that the value of non-linear parameter $|f_{\rm NL}| \sim 1$ induces a similar effect to a few factors of difference in the amplitude of the power spectrum.
