Abstract
A laminated header includes a plate-like unit including: bare members having first flow passages formed therein with no brazing material being applied to each of the bare members; and cladding members having second flow passages formed therein with a brazing material being applied to at least a front surface and a back surface of each of the cladding members. The bare members and the cladding members are alternately laminated so that the first flow passages and the second flow passages communicate with each other. A pipe is joined to the plate-like unit under a state in which an end portion of the pipe is inserted into at least one of the first flow passages or the second flow passages. One of the bare members is laminated on an outermost side of the plate-like unit in a laminating direction of the bare members and the cladding members.
