| 摘要 | An electrical circuit element including a moulded synthetic resin substrate (11), two electrical conductor sets (21-24 and 25-27) carried by the substrate (11), a first of said conductor sets (21-24) including at least one performed metal strip and the second of said conductor sets (25-27) including at least one printed track. The invention further resides in a method of manufacturing an electric circuit element comprising the steps of starting with mould means defining the shape of a desired substrate, positioning within said mould means at least one electrical conductor in the form of a performed metallic strip (21-24), positioning within said mould means, in relation to said strip, a flexible printed circuit including a flexible, electrically insulating backing member (32) with a flexible conductive track (25-27) exposed on one face thereof, the positioning of the strip and the flexible printed circuit in said mould means being such that after moulding said strip and said track will be exposed on the moulded substrate, and introducing synthetic resin material into said mould means to form said substrate (11). | ||||||
