PROBLEM TO BE SOLVED: To provide a working method for obtaining a metallic sheet having a three-dimensional structure which has high degree of freedom of shape by working a thin metallic sheet, the metallic sheet having three-dimensional structure which is obtained by the same method, and the metallic sheet having functional multilayer three-dimensional structure the each layer of which contains a thermal functional material by forming the metallic sheet having a multilayer three dimensional structure by combining the three-dimensional structure metallic sheets. SOLUTION: A metallic sheet 13 is inserted between a pressing female die 11 having a circular opening part and a cylindrical bar-shaped pressing male die 12, and a metallic sheet 13 on which an approximately conical projecting joint part 15 is formed is formed by making the male die 12 penetrate through the female die 11 while rotating the male die 12. A projecting joining part and a joining part without projection of the metallic sheets worked in this way are joined by fitting, welding, adhesion or the like. COPYRIGHT: (C)2005,JPO&NCIPI
