To provide a connecting structure and a connecting member for a heat exchanger in which the heat exchanger can be connected to a receiver tank with a simple structure and a manufacture and attachment are simple with low weight.

In a connecting structure for a heat exchanger for connecting a heat exchanger 1 to a receiver tank 3, a connecting member 6 for connecting the heat exchanger to the receiver tank comprises plate members superposed to have two hollow pipelines. The connecting member 6 abuts on a header pipe with each pipeline corresponding to each communicating hole of the header pipe 2 so that the header pipe and the connecting member are formed integrally. Each pipeline corresponds to and communicates with each through hole of the receiver tank to connect the heat exchanger to the receiver tank. The connecting member 6 is formed by superposing one or two brazing sheets one surface of which is clad with a brazing material.
