Abstract
Provided is a circuit board manufacturing method capable of securing circuit patterns on a plate-like insulator while keeping the relative position between the circuit patterns, and also provided is a circuit board in which the relative position between a plurality of circuit patterns is kept. A first coil () having one turn is formed in a planar shape from a metal plate. Next, a second coil () having four turns is formed in a planar shape from a metal plate, wherein both of the ends () of the coil are linked to other adjacent regions via linking portions (). A pair of the first coil () and the second coil () are then overlapped so as to face each other through a plastic plate () in which a plurality of prepregs are stacked, after which the links by the linking portions () are disconnected.
