Abstract: An interleaved circuit has first branch conductors branching from a first conductor, second branch conductors branching from a second conductor, a metal base, an insulating layer of a dielectric, and a cover resin layer. The metal base comprises an opening. The first branch conductors and the second branch conductors are arranged alternately in a transverse direction of the insulating layer. A slit is formed in the insulating layer and the cover resin layer. The slit comprises a pair of opposite walls and an air gap between the opposite walls. Air introduced into the air gap forms an air layer. The slit extends longitudinally relative to the interleaved circuit along at least a part of the branch conductors.
