Abstract
An electronic device that is capable of keeping the impedance (ground impedance) between a printed circuit board and a shield case low. The electronic device includes a printed circuit board that has ground layer(s) which is conductive and is provided at a location in the thickness direction of the printed circuit board, and the shield case which is disposed on one side of the printed circuit board and consists of a hollow body that has conductivity. A through hole(s) passing through the ground layer is formed in the printed circuit board. A projecting portion(s), which is inserted into the through hole(s), is formed in a projecting manner in the shield case. In a state of being inserted in the through hole(s), the projecting portion(s) is electrically connected to the ground layer via solder.
