Abstract

An aluminum clad member is produced by: disposing a joining assistance member at a joint interface between an Al core member and an Al skin member, which joining assistance member being formed by crossing Al wires with each other in longitudinal and lateral directions to form a grid, and having a structure in which spot-like thick portions having a thickness of 0.2-3.2 mm are formed at intersections of the Al wires and arranged in the longitudinal and lateral directions so as to be spaced apart from each other by a distance of 0.2-13 mm; and performing a hot rolling operation with respect to the thus obtained stack of the Al core member, the Al skin member and the joining assistance member, by partially fixing together those members at their peripheral portions or without fixing together those members, such that the joint interfaces is communicated with an ambient air.
