After mounting the active element 7 and the passive cable 8 on the top and connecting the circuit element on the circuit board 5 to the board 5 and the lead lb of the lead frame through the metal thin #9, transfer mold sealing is performed. [Problems to be Solved by the Invention] In the conventional hybrid integrated circuit structure described above, the circuit board is attached to the island of the metal lead frame using an adhesive. Because it is bonded, the heat dissipation characteristics of the elements mounted on the circuit board are poor. Furthermore, since the circuit board is also thick, there is a limit to how many layers can be added. Therefore, it has the disadvantage that it is difficult to achieve high integration.

Furthermore, elements that require heat dissipation are mounted directly on the metal thin film to improve the heat dissipation characteristic E. Furthermore, a conventional circuit board is placed on the metal thin film, and the two metal thin film circuit boards are connected to each other before the exterior resin is applied. It is being sealed.
