摘要： An electronic component includes a board having first and second electrode pads on one surface of the board; and a multilayer capacitor. The multilayer capacitor comprises: a capacitor body comprising a dielectric layer and a plurality of internal electrodes, disposed horizontally with respect to a mounting surface of the capacitor body facing the one surface of the board, and external electrodes disposed on both end portions of the capacitor body and connected to exposed portions of the internal electrodes, respectively. The electronic component satisfies Lp/Lc≤1.35, where a distance between outer edges of the first and second electrode pads is defined as Lp, and a length of the multilayer capacitor is defined as Lc.

摘要： An element body includes a principal surface arranged to constitute a mounting surface and a first side surface adjacent to the principal surface. An external electrode includes a first electrode portion disposed on the principal surface and a second electrode portion disposed on the first side surface. The first electrode portion includes a sintered metal layer, a conductive resin layer formed on the sintered metal layer, and a plating layer formed on the conductive resin layer. The second electrode portion includes a first region and a second region. The first region includes a sintered metal layer and a plating layer formed on the sintered metal layer. The second region includes a sintered metal layer, a conductive resin layer formed on the sintered metal layer, and a plating layer formed on the conductive resin layer. The second region is located closer to the principal surface than the first region.
