Abstract
PURPOSE: To make an establishment of a middle point easy together with to enable obtaining a coupling degree simply by forming primary and secondary coils with printed wirings.
CONSTITUTION: On an upper surface 25a of a printing base plate 25 a primary coil L1 of almost U letter shaped pattern is formed. At an external side of this coil L1 one portion of a secondary coil L2 is formed so as to surround it, maintaining a determined spacing W from it and as of a similar pattern as L1 together with inside of L1, L2a, L2b of L2 remainder are formed. And a point of one half of a full length of the secondary coil L2 is made to be a middle point 22c. In this manner as L1, L2 can be formed to maintain a perfect parallel condition at all portions, a coupling degree is made high at a same time a coupling degree Ma=Mb can be achieved.
