PROBLEM TO BE SOLVED: To enable sure and highly airtight brazing on a periphery of one of communication holes through which a high pressure refrigerant passes.SOLUTION: Plates 3 and 4 which have respective pairs of first communication holes 34 and 44 and respective pairs of second communication holes 35 and 45 and are alternately laminated. Between adjacent plates 3 and 4, a first refrigerant circuit 81 and a second refrigerant circuit 82 are alternately provided. A first spacer 5 is interposed around each of the first communication holes 34 and 44 in the first refrigerant circuit 81. A second spacer 6 is interposed in the second refrigerant circuit 82 around each of the first communication holes 34, 44. |
