A flat plate frame is formed, which is flat plate-shaped, which has an opening penetrating its front and rear surfaces and groove terminal patterns formed on its front surface, and which contains a semi-cured thermosetting resin. Then, an insulating substrate is disposed on the rear surface so as to cover the opening of the flat plate frame, external connection terminals are disposed on the terminal patterns, and heating is carried out. As a result, a terminal package to which the insulating substrate and external connection terminals are firmly joined is produced using the flat plate frame. The external connection terminals included in the terminal package are reliably and firmly joined to the terminal package. Therefore, the external connection terminals are not displaced when wires are bonded to the external connection terminals.
