1. An electronic component comprising:
an electronic element; and
an interposer board; wherein
the electronic element includes:
a 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 joined with one of the pair of multilayer body main surfaces or one of the pair of multilayer body side surfaces;
the interposer board is an alumina board; and
a mark portion includes Si and alumina, and is provided on one of the pair of board main surfaces.
