    Abstract: PROBLEM TO BE SOLVED: To provide a paste for Al-Cu brazing which can satisfactorily join aluminum or an alloy thereof and copper or an alloy thereof, and is excellent in storage stability and productivity, and to provide an Al-Cu brazing method using the paste for Al-Cu brazing.SOLUTION: In a paste for Al-Cu brazing, (a) an Al-Cu-Si-Zn-based alloy, (b) Cs-Al-F compound-based flux, (c) a binder formed of a butyl rubber and/or a methacrylic resin, and (d) a hydrocarbon organic solvent are contained. The content ratio of (a) is 40 to 80 pts.mass. and the content ratio of (b) is 20 to 60 pts.mass. with respect to 100 pts.mass of the total of (a) and (b). The content ratio of (c) is 0.1 to 10 pts.mass. with respect to 100 pts.mass of the total of (a), (b), and (c). The viscosity at 25°C which is measured by a spiral pump type viscometer (stirring speed of 10 rpm and amount of measured sample of 150 mL) is 1 to 300 Pa s.
