Abstract ： The diquark condensate susceptibility in neutral colour superconductor at moderate baryon density is calculated in the frame of the two-flavour Nambu--Jona--Lasinio model with the mean field approximation. When colour chemical potential is introduced to keep charge neutrality, the diquark condensate susceptibility
