PROBLEM TO BE SOLVED: To obtain a method for manufacturing a refrigerating-cycle-constituting body, in which growth the crystal-grain size of a metal sheet is restrained, and thinning of the sheet, improvement of production, and cost reduction can be attained by reducing the time for the metal sheet of the refrigerating-cycle constituting body to be exposed to high temperature. SOLUTION: In the refrigerating-cycle constituting body, channels 5c, 5d are formed by lamination joint with a jointing means in a pair of metal sheets 5a, 5b to form a refrigerant flow path. The jointing means is composed of a press means 10 comprising a bottom force 10a and a top force 10a and a heating means. The heating means and grooves 10f of almost the same shape as the channels 5c, 5d of the sheets 5a, 5b respectively are made in either one or both of the sheets 5a, 5b. The pair of sheets 5a, 5b are clamped by the press means 10 with brazing filler 5e inserted between them to be brazed by the heating means under pressure of predetermined force.
