Multilayer inductors have recently been actively researched for miniaturization of electronic components. A typical laminated inductor is manufactured by printing and laminating a plurality of electrically insulating magnetic ferrite layers and a plurality of conductor pieces for forming a coil alternately so that the ends of the conductors are connected, and then firing and integrating them. ing. This laminated inductor has many advantages, such as being small, having high mechanical strength, and having a rectangular parallelepiped shape.

The conductor pattern forming the coil of the laminated inductor portion in the composite component is drawn out to the peripheral end face of the laminated inductor, and then a conductive paste is applied and baked to form an external terminal. However, since the conductor pieces for forming the coil are thin, from a few μm to a dozen μm, and are formed by printing, even if they are pulled out to the side end face of the laminate, only a small amount of this thickness will be exposed. Therefore, when applying conductive paste to the end face, a sufficient electrical connection may not occur.
This caused the defect. Therefore, a lead-out conductor structure with good electrical connectivity is desired.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following explanation, the ferrite layer is a raw layer formed by printing a paste containing a mixture of high permeability magnetic ferrite powder and a binder resin such as butyral, and becomes an insulating magnetic material after firing. It is usually formed by overprinting several times. The conductor pieces are formed by printing a paste of Pd-Ag or other metal powder mixed with a binder resin. Also, the external terminals are formed from a similar conductive paste, but unlike the conductor strips, baking may be performed at relatively low temperatures. In addition, the dielectric layer is also a raw sheet formed by printing a paste mixed with powder such as barium titanate and binder resin, and is fired together with the inductor section to become a predetermined dielectric. . As the electrode for the capacitor, the same conductor piece as described above may be used. On the other hand, as the resistor, a paste obtained by mixing powder such as Ru2 O with a binder resin can be used. Further, a large number of composite parts are manufactured by simultaneously printing on a wide substrate (for example, a polyester film spread on a smooth A1 board), but for the sake of explanation, only one will be produced.
