Abstract
A conductive pattern of a first layer isolated by an isolation trench is formed on a conductive foil, and a plurality of layers of the conductive patterns are formed thereon to create a multilayered wiring structure, and furthermore, a circuit element is mounted and molded with an insulating resin and the back surface of the conductive foil is etched. It is possible to implement a method of manufacturing a circuit device which provides very power saving and is suitable for mass production, then the circuit device having conductive patterns of a multilayered structure are provided.
