We study the effect of the scotogenic dark matter on the primordial black holes (PBHs) and vice versa. We show that if the PBHs evaporate in the radiation dominant era, the upper limit of the initial mass of the PBHs M_{in} should be constrained as 10^4 < M_{in}/M_{Pl} < 10^{10} for O(1) TeV scotogenic dark matter, O(1) TeV is the most appropriate energy scale in the scotogenic model. On the other hand, if the PBHs evaporate in the PBH dominated era, a quite heavy scotogenic dark matter m_{DM} > 10^9 GeV for M_{in}/M_{Pl} \sim 10^{13} may be allowed. This talk based on arXiv:2101.01921v3 (to be published in International journal of modern physics A).
