[Problems to be solved by the device]

 However, in the case of the wiring as shown in FIG. 4, it is necessary to provide the through hole 6 at the tip of the wiring conductor 5 and the wiring conductor 7 on the back surface of the substrate 2. In the case of the wiring as shown, it is necessary to provide the jumper wire 12 and solder it, which causes a problem that the wiring process becomes complicated.

【Example】

 FIG. 1 is a schematic view showing a state in which an electronic component according to an embodiment of the present invention is mounted on a substrate. 1 (a) is a plan view and FIG. 1 (b) is a sectional view. In FIG. 1, 1 is an electronic component, 2 is a substrate made of an insulating resin material, 3 is an external terminal, 4 is a wiring terminal, and 5 is a wiring conductor.

As shown in FIG. 1, the electronic component 1 has a plurality of elements (not shown) forming a predetermined electronic circuit (not shown) inside the main body 1a, and is provided outside the main body 1a. , A plurality of external terminals 3 electrically connected to each element and two wiring terminals 4. The wiring terminals 4 are electrically connected to each other by the conductors 4a inside the main body 1a, and are electrically insulated from the external terminals 3. Thus, the electric signal input to the wiring terminal 4 does not contribute to the operation of the electronic circuit inside the main body 1a.

When the electronic component 1 as described above is mounted on the substrate 2, each wiring is electrically connected to another electronic component (not shown) for convenience of wiring. It is assumed that it is necessary to provide a wiring conductor (not shown) for connecting the conductors 5 on the electronic component 1 in an overlapping manner. In such a case, a desired wiring can be easily provided by electrically connecting each wiring conductor 5 to the wiring terminal 4.

As described above, since the two wiring terminals 4 electrically insulated from the external terminals 3 are provided outside the main body 1a and the respective wiring terminals 4 are electrically connected inside the main body 1a, the electronic component Even if it becomes necessary to provide a wiring conductor on top of each other, by connecting the wiring conductor 5 electrically connected to another electronic component to each wiring terminal 4, each wiring conductor 5 can be easily connected. The two can be electrically connected.

Therefore, it is not necessary to provide the through hole 6 and the jumper wire 12 as in the related art, and the wiring process can be simplified. Furthermore, since it is not necessary to provide the wiring conductor 13 that bypasses the electronic component 10 as in the related art, it is possible to increase the degree of freedom of wiring by other wiring conductors on the substrate 2. Note that any number of wiring terminals 4 may be provided as long as the number of wiring terminals 4 is two or more. Further, the connection between the wiring terminals 4 is arbitrary. The electronic component 1 may be any one having a plurality of external terminals such as a resistor array, a monolithic IC and a hybrid IC.
