Abstract: 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.

Abstract: An electronic component is provided with an element body and terminal electrodes. The terminal electrodes include sintered metal layers and conductive resin layers. A first length, which is a length of the sintered metal layers in a first direction at end portions of a side surface in a second direction, is shorter than a second length, which is a length of the sintered metal layers in the first direction at central portions of the side surface in the second direction. A third length, which is a length of the conductive resin layers in the first direction at the end portions, is shorter than a fourth length, which is a length of the conductive resin layers in the first direction at the central portions. A difference between the fourth length and the third length is larger than a difference between the second length and the first length.

Abstract: An electronic component includes an element body having a pair of end surfaces opposing each other and a side surface adjacent to the pair of end surfaces, and an external electrode disposed on at least the end surface. The external electrode includes a conductive resin layer located on at least the end surface. A first thickness of the conductive resin layer located on a central region of the end surface is greater than a second thickness of the conductive resin layer located on a peripheral region of the end surface.

Abstract: An external electrode includes a sintered metal layer disposed on at least an end surface and a conductive resin layer disposed on the sintered metal layer. The sintered metal layer includes a first portion, a second portion, and a third portion. The first portion is disposed at a central region of the end surface. The second portion is disposed at a part of a peripheral region of the end surface, and extends to an edge portion of the end surface from the first portion. The third portion is disposed at a remaining part of the peripheral region of the end surface. The thickness of the second portion is less than that of the first portion. The thickness of the third portion is less than that of the second portion. The first portion, the second portion, and the third portion are covered with the conductive resin layer.
