PROBLEM TO BE SOLVED: To solve a problem in which a printed board, a ceramic board, a flexible sheet, or the like is used as a support board integrally to constitute a circuit device, where the support board is fundamentally an unnecessary member, and the thickness of the support board causes the circuit device to become larger in size. SOLUTION: A conductive foil 60 is pasted on a support board SS, separation grooves 54 are cut in the conductive foil 60, a circuit element is mounted on the conductive foil 60, and then the conductive foil 60 is coated with an insulating resin 50, Thereafter, a sealed body sealed up with the insulating resin 50 is separated from the support board SS. Therefore, a support board and a circuit device are not integrated, and a circuit device composed of a conductive circuit 51 and a circuit element 52 supported by the insulating resin 50 can be realized. Moreover, the circuit is equipped with wirings L1 to L2 which are integral components, and a curved structure 59 or an overhang 58 are provided, so that the insulating resin 50 will not slip out. |
