A tube is formed by brazing first and second plates, and is connected to a pipe through a connection block being brazed to a contacting surface of the first plate. A brazing material is clad on an inner surface of the first plate opposite to the contacting surface, and a hole penetrating through the first plate is formed in the first plate at a position corresponding to the connection block. Thus, during brazing, the brazing material clad on the inner surface of the first plate is supplied to the contacting surface through the hole by capillary phenomeno...
