ABSTRACT:
A shield structure having a plurality of hollow columnar base members arranged with intervals therebetween along the periphery of a section to be shielded on a surface of a circuit board, and a shield cover with a peripheral wall having insertion pieces arranged along the edge thereof at positions corresponding to the positions where the base members are arranged. Each base member has a cut in at least a top surface thereof. The cut forms an elastically deformable tongue portion having a free end at a position where the corresponding insertion piece of the shield cover is inserted. The tongue portion is elastically deformed toward the inner space of the base member by an insertion force applied when the corresponding insertion piece of the shield cover is inserted into the cut at the free end. The tongue portion functions as an elastic holding portion that retains and fixes the shield cover on the base member by applying an elastic resilient force such that the free end thereof presses against the insertion piece of the shield cover.
