The correlation functions for the Ising model with one bond defect can be exactly expressed by the ones for the pure Ising model. By using these expressions, the internal energy of the Ising model with dilute impurities is obtained. The critical behaviour of the impure Ising model is discussed and the shift of the critical temperature is determined.
