We continue our study of entanglement entropy in the holographic superconducting phase transitions. In this paper we consider the p-wave holographic insulator/superconductor model, where as the back reaction increases, the transition is changed from the second order to a first order one. We find that unlike the s-wave case, there is no an additional first order transition in the superconducting phase. We calculate the entanglement entropy for two strip geometries. One is parallel to the super current, and the other is orthogonal to the super current. In both cases, we find that the entanglement entropy monotonically increases with respect to the chemical potential.
