A surface mounting package includes a metal base with a lower surface having a through hole, a metal lead arranged to be inserted into the through hole, an insulating material filling in an internal space defined by the metal base, a cap covering the metal base as a lid, and an electronic part component arranged at a surface on the internal space side of the metal lead. The internal space is held at an air-tight atmosphere. The metal base has a lower surface positioned on the same plane as a lower surface of the metal lead or the insulating material, the same plane forming a plane to be attached to a mounting board.
