ABSTRACT:
A unitary circuit structure has an electric and/or optical transmission medium. The structure includes at least one of an optical signal transmission medium (22), an electric signal transmission medium (1, 8, 21, 41), and an electric power transmission medium (23) which are insert-molded in a plastic which forms a housing (7, 24) for electronic and electric devices and parts. The circuit structure serves as both conductive circuits and housing so that the electronic and electric devices and parts can be wired and mounted at high density.
