Abstract: A multilayer electronic component includes an element body having an internal electrode layer and a dielectric layer. These layers are substantially parallel to a plane including a first axis and a second axis and are alternately laminated along a third axis direction. A pair of side surfaces facing each other in the first axis direction of the element body is respectively equipped with an insulating layer. A pair of end surfaces facing each other in the second axis direction of the element body is respectively equipped with an external electrode electrically connected to the internal electrode layer. The insulating layer has a mountain portion formed on a peripheral edge of the side surface and a plane portion of a central portion of the side surface.

Abstract: A multilayer electronic component includes an element body having an internal electrode layer and a dielectric layer. These are substantially parallel to a plane including a first axis and a second axis and are alternately laminated along a third axis direction. Side surfaces facing each other in the first axis direction are respectively equipped with an insulating layer. End surfaces facing each other in the second axis direction are respectively equipped with an external electrode. The insulating layer integrally has an insulating layer extension portion covering part of the end surfaces facing each other in the second axis direction. W1/W0 is 1/30 to less than ⅜, where W0 denotes a width along the first axis, and W1 denotes a width along the first axis of the insulating layer extension portion. The external electrode covers at least part of the insulating layer extension portion.
