Abstract

Abstract The specification discloses a circuit structure, wherein the electric and/or optical transmission medium or media comparising 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) are insert-molded in plastics which is a housing (7, 24) for electronic and electric devices and parts. The circuit structure serves both for conductive circuits and housing so that the electronic and electric devices and parts can be wired and mounted at high density.
