Patent ID: 8749338

Claim:
A laminated electronic component having a structure whereby multiple insulator layers, each with wires comprising conductors formed on a surface, are laminated and said wires on the respective insulator layers are connected, wherein adjacent wires sandwiching each insulator layer are inter-connected by connection conductors formed by conductors in a manner filling and projecting on top of via holes that penetrate the insulator layer; the connection conductors are recessed at a center to become lower than outer peripheries of the via holes; the wires are coil conductors constituting a part of a spiral coil conductor and their inter-connection by the connection conductors form the spiral coil conductor in a laminate of multiple insulator layers; and in an insulation layer between the wire having the connection conductor formed on another insulation layer and an adjacent wire above the aforesaid wire with an insulator layer provided in between, a thickness of the insulator layer between the connection conductor and the adjacent wire is greater than a thickness of the insulator layer between a wiring part of the aforesaid wire other than the connection conductor and the adjacent wire.
