<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic induction module which can adjust a resonant frequency, is reduced in size and thickness and is reduced in cost. <P>SOLUTION: This electromagnetic induction module has a structure in which a loop-like antenna 2 made of a spiral conductor wiring pattern is provided on an insulation substrate 1, and a plurality of capacitors 3 for matching are provided in the loop of the loop-like antenna 2. The plurality of these capacitors 3 are mounted on a comb-like conductive wiring pattern 6. Two or more kinds of capacitors are used for the capacitors 3, and a conductive wiring 6a of the conductive wiring pattern 6 is cut to adjust a resonant frequency. Further, a soft magnetic body sheet 4 having openings 7 provided on portions equivalent to a portion where the external connection terminals 5a, 5b and 5c are provided and on a portion where the plurality of capacitors 3 are provided is disposed on the insulation substrate 1. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
