Abstract
Entry of resin into a cylindrical electrode can be suppressed without excessively increasing the number of parts and without unnecessarily damaging members. For this purpose, a semiconductor chip and a cylindrical electrode are mounted on one main surface of substrate. The substrate, the semiconductor chip, and the cylindrical electrode are sealed with resin material such that the cylindrical electrode has one end mounted to the substrate and the other opposite end at least exposed. After the step of sealing, an opening extending from the other end of the cylindrical electrode to a cavity in the cylindrical electrode is formed. Before performing the step of forming an opening, the other end of the cylindrical electrode is closed.
