PROBLEM TO BE SOLVED: To enhance the joining strength of joined metal plates by filling the bent portion of each metal plate with an adhesive, without increasing working manpower in manufacture. SOLUTION: The invention relates to a method for manufacturing joined metal plates 1 comprising an upper metal plate 10 and a lower metal plate 20. The upper metal plate 10 is continuously formed via an upper bent portion 13 where an upper wall portion 11 which extends vertically and an upper flange portion 12 which extends crosswise are formed in a curve. The lower metal plate 20 is continuously formed via a lower bent portion 23 where a lower wall portion 21 which extends vertically and a lower flange portion 22 which extends crosswise are formed in a curve. The upper metal plate 10 and the lower metal plate 20 are formed so that the upper flange portion 12 and the lower flange portion 22 separate crosswise from each other toward the upper bent portion 13 and the lower bent portion 23, and the upper flange portion 12 and the lower flange portion 22 are pinched and welded in a state of interposing the adhesive 30 between the upper flange portion 12 and the lower flange portion 22.
