<p>PURPOSE: To provide a multilayer printed-coil board capable of increasing piece extracting numbers from one board without externally exposing conductor part excluding the outer connecting terminal even if it is externally cut off. CONSTITUTION: The multilayer printed-coil board is provided with a laminated layer body 3 comprising a plurality of laminated base materials 2, also a plurality of spiral patterns 4 comprising coils 6, a core containing hole 7 in the inner region of the coil 6 and a plurality of sectional plated through holes 10. The patterns 10 can be pulled out of specific positions of the spiral patterns 4 passing through the inside of the laminated body 3. At this time, respective pulled out patterns 4 are electrically connected to respective sectional plated through holes 10. Accordingly, in such a constitution, respective sectional plated through holes 10 can fill the roles of the outer connecting terminals.</p> |
