Claim 0:
1. An electronic component comprising:
an electronic element; and
an interposer board; wherein
the electronic element includes:
a rectangular or substantially rectangular multilayer body including dielectric layers and internal electrode layers which are alternately laminated, a pair of multilayer body end surfaces orthogonal or substantially orthogonal to the internal electrode layers, a pair of multilayer body side surfaces orthogonal or substantially orthogonal to the multilayer body end surfaces, and a pair of multilayer body main surfaces orthogonal or substantially orthogonal to the multilayer body end surfaces and the multilayer body side surfaces; and
external electrodes each on a respective one of the pair of multilayer body end surfaces of the multilayer body and connected to the internal electrode layers;

the interposer board includes a pair of board end surfaces, a pair of board side surfaces orthogonal or substantially orthogonal to the board end surfaces, and a pair of board main surfaces orthogonal or substantially orthogonal to the board end surfaces and the board side surfaces;
one of the pair of board main surfaces is located in a vicinity of the electronic element and joined with one of the pair of multilayer body main surfaces in a vicinity of the interposer board;
the interposer board is an alumina board;
the external electrodes each include a Ni plated layer, and a first Sn plated layer that covers an outer surface of the interposer board in a vicinity of at least one of the pair of board end surfaces;
a Ni plated layer is provided on the interposer board in the vicinity of the at least one of the board end surfaces; and
the Ni plated layer of the external electrode is not connected to the Ni plated layer of the interposer board.
