PROBLEM TO BE SOLVED: To provide a printed wiring board acting as a base for easily conducting a planar coil with different turn numbers.;SOLUTION: On both faces of an insulating substrate served as a base for a printed wiring board, first and second conductors that form loops around predetermined regions (holes) are arranged respectively, and third and fourth conductors, a selective connection, and an inter-substrate connection for selectively connecting the first and the second conductors are arranged. Regions symmetric to the selective connection with respect to a base line passing through the holes are defined as regions (holes) where conductors are not formed. A plurality of the printed wiring boards are laminated by contacting the first surfaces or the second surfaces thereof, and the first and second conductors are serially connected alternately to construct a planar coil with a predetermined turn numbers.;COPYRIGHT: (C)2013,JPO&INPIT
