Claim:
1. A method for manufacturing a combined wiring board, comprising: preparing a plurality of wiring boards; preparing a metal frame having a plurality of opening portions configured to accommodate the plurality of wiring boards, respectively; positioning the plurality of wiring boards in the plurality of opening portions in the metal frame; and forming a plurality of crimped portions in the metal frame by plastic deformation such that sidewalls of the metal frame in the opening portions bond sidewalls of each of the wiring boards, wherein: the plurality of crimped portions is formed such that the crimped portions in the metal frame have amounts of the plastic deformation which are set different for positions of the crimped portions in the metal frame; and the plurality of crimped portions in the metal frame is positioned such that each of the wiring boards has a plurality of corners each of which is interposed between two crimped portions of the plurality of crimped portions in the metal frame, and the amounts of the plastic deformation are set different for the crimped portions in the metal frame such that one of the two crimped portions at each corner of a wiring board is positioned closer to the center of the wiring board and has a larger amount of the plastic deformation with respect to the other one of the two crimped portions.
