2. Description of the Related Art
A multilayer capacitor described in Japanese Unexamined Patent Application Publication No. 2004-140183 is a known example of an electronic component of the related art. FIG. 22 is a front view of a multilayer capacitor 500 described in Japanese Unexamined Patent Application Publication No. 2004-140183.
The multilayer capacitor 500 includes a multilayer body 502, internal conductors 504 and 506, led out electrodes 508 and 510 and external electrodes 512 and 514. The multilayer body 502 is formed by stacking a plurality of dielectric layers on top of one another. In FIG. 22, the surface of the multilayer body 502 on the lower side is a mounting surface. The internal conductors 504 and 506 are stacked together with the dielectric layers and face each other with a dielectric layer interposed therebetween, whereby an electrostatic capacitance is formed. The led out electrodes 508 and 510 are respectively connected to the internal conductors 504 and 506 and are led out to the mounting surface. The external electrodes 512 and 514 are respectively connected to the led out electrodes 508 and 510. In the above-described multilayer capacitor 500, by making the distance between the led out electrodes 508 and 510 and the distance from the internal conductors 504 and 506 to the mounting surface maintain a predetermined relationship with each other, a decrease in the equivalent serial inductance is achieved.
However, in the multilayer capacitor 500 described in Japanese Unexamined Patent Application Publication No. 2004-140183, since the external electrodes 512 and 514 are close to each other, there is a risk that the external electrode 512 and the external electrode 514 will become connected to each other with solder when the multilayer capacitor 500 is mounted on a circuit substrate. That is, with the multilayer capacitor 500, there is a risk of a short circuit occurring.
