A multilayer bodyis obtained by stacking a plurality of insulator layers in which an inner conductor and a via hole conductor are formed. Outer electrodesthroughconnected to the inner conductor layers are formed on the opposite side surfaces of the multilayer bodyWhile the two outer electrodesandare formed so as to extend from one principal surface to the other principal surface of the multilayer bodythe other outer electrodesthroughare formed so as to extend from one principal surface to an exposed portion of the inner conductor on the multilayer bodyor formed so as not to reach the other principal surface. In addition, the widths of the outer electrodesthroughmay differ from one another.

Electronic component

In an electronic component, a peripheral portion of an external terminal electrode is thicker than a center portion thereof, and at least a portion of the peripheral portion is buried in a component main body. A surface of the external terminal electrode and a principal surface of the component main body are located on the same plane. An electrically insulating coating layer is arranged along the principal surface of the component main body so as to cover at least a portion of the peripheral portion of the external terminal electrode. An end portion of the coating layer is in contact with a thickest portion of the peripheral portion of the external terminal electrode in the principal surface of the component main body. The coating layer and the surface of the external terminal electrode are located on the same plane.
