A header tank for a high pressure heat exchanger is provided to improve anti-pressure property of the header tank, and to prevent clogging of a tube insertion hole during brazing by forming an inclined guide portion in the tube insertion hole of the tank. A header tank for a high pressure heat exchanger comprises a tank(10) and a header(20). The tank forms a refrigerant flow path(11) in the middle of a length direction and a plurality of tube insertion holes(12) in an orthogonal direction of the refrigerant flow path. The header is coupled to the tube insertion holes of the tank and forms a plurality of slots(21) corresponding to the tube insertion holes. The tube insertion holes of the tank forms a guide portion(13) inclined by a cutting tool, and allows the tube(30) to be contacted with the guide portion. |
