A conductive column is provided in the second base, and a first groove and a second groove are further provided at the second face. The first groove is located above the conductive column, and the second groove exposes at least part of a side surface of the conductive column. The protruding portion of the electrical connection column is located in the second groove, and part of a side surface of the electrical connection column and part of the side surface of the conductive column overlap in staggered way in a direction perpendicular to the first face or the second surface. At least part of the welded structure is filled in the first groove.
