Abstract

A multilayered LC composite component includes a main body having a pair of side surfaces, a pair of end surfaces, and an upper surface and a lower surface. Ground-side terminal electrodes are disposed at the center of the side surfaces and hot-side terminal electrodes are disposed along edges of the side surfaces. Each of the hot-side terminal electrodes includes an end surface extended portion extending to each of the end surfaces. The end-surface extended portion is arranged so that at least the approximate center of each of the end surfaces is exposed.

Description

technical field [0001] The present invention relates to a multilayer LC composite element and its manufacturing method. Specifically, the present invention relates to an improvement in the layout of terminal electrodes disposed on the outer surface of a device main body. Background technique [0002] Figure 13 is a perspective view showing a known multilayer LC composite element 1 related to the present invention. Figure 14 is displayed as Figure 13 A cross-sectional view of the internal structure of the multilayer LC composite element 1 shown. [0003] The multilayer LC composite element 1 comprises a rectangular body 2 . The main body 2 includes a pair of side surfaces 3 and 4 facing each other, a pair of end surfaces 5 and 6 facing each other, and an upper surface 7 and a lower surface 8 facing each other. [0004] The main body 2 has a multilayer structure including a plurality of electrically insulating layers, and has a capacitor element 10 and an inductor elemen...
