PROBLEM TO BE SOLVED: To provide a plate heat exchanger that can secure adherence of a joint and prevent dislocation of the joint when two plates are jointed.SOLUTION: A heat exchanger 10 is a plate heat exchanger manufactured by laminating a flow passage 21 formed by jointing two press-molded metal plates 80, 90. Edge parts 85, 86, 95, 96 which are joints of the metal plates 80, 90 include slopes inclined to a reference plane of the metal plates 80, 90. When the metal plates 80, 90 are jointed, the slopes are arranged to lap opposite each other. |
