Abstract: A laminated electronic component includes an element body and a conductor. The element body is formed by laminating a plurality of element-body layers. The element body has a first face, a second face, and a pair of third faces. The conductor is disposed on the element body and has an L shape. The conductor has an exposed face exposed on the first face and the second face. The exposed face includes a plurality of divided regions divided by the element body. The length of each divided region in a dividing direction is longer than a distance with which the plurality of divided regions is separated from each other and longer than a distance with which the exposed face and the pair of third faces are separated from each other.

Abstract: A laminated electronic component includes an element body and a pair of conductors. The element body is formed by laminating a plurality of element-body layers in a first direction. The pair of conductors is formed by laminating a plurality of conductor layers in the first direction. The pair of conductors is provided to the element body in such a way as to be separated from each other in a second direction orthogonal to the first direction. At a cross section orthogonal to the first direction, the pair of conductors has an uneven portion and the element body has an uneven portion engaged with the uneven portion of the pair of conductors.
