PRINTED BOARD COMPRISING COIL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a printed board comprising a coil element of small circuit pattern with good high-frequency characteristics and Q factor. SOLUTION: On an insulating layer 6, a coil body 14 is formed whose outside diameter is 0.1-3 mm by patterning a conductive layer in substantially spiral form. The printed board comprises a coil element 2 in which both ends of the coil body act as an input/output terminal 24. Thus, a high-frequency characteristics including Q factor is kept high.
