Zusammenfassung:	A method for producing an aluminum joined body includes a step of forming a flare joint by using a first aluminum member and a second aluminum member; and a step of performing laser welding by irradiating a groove of the flare joint with a laser beam having a beam diameter of 0.8 to 3.5 mm while feeding a filler material to the groove, the filler material being made of an aluminum alloy containing, in percent by mass, 1.0% to 3.0% of Mg, 0.50% to 1.0% of Mn, 0.05% to 0.20% of Cr, and 0.05% to 0.20% of Ti, with the balance being aluminum and incidental impurities.
