The present invention relates to an integrated connector and a heat exchanger including the same, in which a connector main body is formed by pressing one pipe, a cap is press-fitted into the connector main body, such that the integrated connector is formed so that an interior of the connector main body is blocked by the cap. Therefore, the number of components used to manufacture a connector, which connects and securely couples a header tank and a gas-liquid separator, may be reduced, the integrated connector may be easily manufactured, and a brazing defect may be reduced at portions where the integrated connector is joined to the header tank and the gas-liquid separator of the heat exchanger.
