And the heat is efficiently dissipated from the heat dissipating fins. Further, both ends in the longitudinal direction are opened on one surface of the electronic component storage chamber to form a continuously enclosed cylindrical electronic component storage chamber, and the surface of the electronic component storage chamber facing the horizontal substrate is cut inward. Since the electronic component pressing spring piece is integrally formed, both ends in the longitudinal direction are opened on one surface of the horizontal substrate, and the cylindrical electronic component storage chamber that is continuously surrounded and the horizontal substrate of the horizontal substrate is formed along the longitudinal direction. The electronic component pressing spring piece can be easily formed by cutting the extruded material having a plurality of fins on the surface and performing a single press working on the obtained member.
