Abstract
In a step of covering a rear face resist, by recognizing position of a positioning mark exposed at a rear face of a conductive foil, position recognition of a conductive pattern of the rear face of every block or every conductive foil is performed indirectly, and a resist layer is formed except an opening portion forming the scheduled rear face electrode on the conductive pattern. Therefore, a method of manufacturing a circuit device shortened in time.
