Zusammenfassung:An object of the present invention is to provide an interconnect structure in which the current capacity of an interconnect pattern involving a large amount of current is increased without preventing miniaturization of signal lines and increasing film thickness. To accomplish this object, the present invention is configured as an interconnect structure including a resin layer; and interconnects formed on the resin layer, wherein the resin layer has a plurality of parallel grooves in an area in which the interconnects are formed, and the interconnects are formed of a plating film created on a resin layer front surface in the area, in which the interconnects are formed, and on inner wall surfaces of the plurality of grooves.
