To provide a rolled plate capable of preventing the shortage of a height of a projection for a side wall at forming a plate-shaped body for manufacturing a flat tube by rolling.
This rolled plate is used for forming the plate-shaped body 20 for manufacturing the flat tube. The plate-shaped body 20 for manufacturing the flat tube comprises upper and lower wall forming portions 21, 22, a connecting portion 23 connecting the upper and lower wall forming portions 21, 22 and further forming one of side walls, and the projections 9, 11 for the side wall integrally molded on a side edge at a side opposite to the connecting portion 23 of the flat wall forming portions 21, 22, and made to abut each other when the plate-shaped body 20 is folded into a hairpin shape at the connecting portion 23. The rolled plate is composed of an aluminum brazing sheet having aluminum brazing filler metal layers on both faces of a core material formed of an Al-Mn alloy. An r value of the core material of the aluminum brazing sheet is 0.65 or smaller, and an average aspect ratio of crystalline particles of the core material is 5 or smaller.
