Multilayer electronic component

A multilayer electronic component comprising an element body having an internal electrode layer and a dielectric layer, both of which are substantially parallel to a plane including a first axis and a second axis and are alternately laminated along a third axis direction, wherein

• 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 integrally has an insulating layer extension portion covering part of the end surfaces facing each other in the second axis direction of the element body,
• W1/W0 is 1/30 to less than ⅜, where
• W0 denotes a width along the first axis of the element body and
• W1 denotes a width along the first axis of the insulating layer extension portion formed on the end surfaces in the second axis direction of the element body, and
• the external electrode covers at least part of the insulating layer extension portion formed on the end surfaces in the second axis direction of the element body.
