Shielding structure for use in an electronic device comprising a housing and an electronic substrate which is arranged in the housing and which includes electronic parts, wherein the housing includes at least a surface facing the electronic parts, the surface being made of an electrically conductive substance. There is disposed a shielding member made of electrically conductive material comprising a frame-shaped section disposed on the printed board to surround a periphery of the electronic parts and a leaf spring section disposed to project from an upper-edge section of the frame-shaped section toward the inside of the frame-shaped section and upwardly in an inclined direction. The shielding member is disposed on the electronic substrate, and the surface made of an electrically conductive substance of the housing pushes the leaf spring section to be brought into contact therewith.
