A heat exchanger includes tubes, a core plate connected to the tubes, a tank connected to the core plate to be in communication with the tubes and a sealing member sealing a connecting portion between the core plate and the tank. The core plate has a groove portion including at least a base wall and an inner side wall to define a groove having a loop shape. The sealing member is disposed in the groove portion to be in contact with the inner side wall at least at two opposite locations of the loop shape. Alternatively, the sealing member is disposed in the groove portion to be in contact with at least one of the inner side wall and an outer side wall opposed to the inner side wall, and a substantially middle portion of a width of the sealing member is pressed by a projection of the tank.
