A heat exchanger comprises a main body and at least one header-held members, with the main body having a plurality of heat exchanging tubes whose both ends are connected to headers in fluid communication with them, wherein the header-held members are selected from a group consisting of a bracket and an external pipe-connecting member which are attached to the header. The header-held members each comprise a header-surrounding portion which is fitted sideways on and then brazed to the header while remaining self-retained on it, whereby the header-held member can be easily and rigidly secured to the header.
