Abstract
A joined body which is formed by, first, an aqueous solution containing an oxide film remover is disposed on a junction region of a first metal plate. Then, with the aqueous solution remaining on the first metal plate, a second metal plate is placed on the first metal plate. Thereafter, a load is applied to junction regions of the first metal plate and the second metal plate in the vertical direction, thereby joining the first metal plate and the second metal plate together to form a junction portion.
