A shield cap for protecting an electronic component includes a cap member having a side wall portion and a ceiling portion, a conductive film formed on the cap member such that the conductive film is formed to shield electromagnetic waves, and a metal layer formed on a portion of the side wall portion such that the metal layer is interposed between the conductive film and the portion of the side wall portion. The side wall and ceiling portions are forming an accommodation space to accommodate an electronic component, and the metal layer is formed on a surface of the side wall portion on the opposite side of a surface of the side wall portion facing the ceiling portion and interposed between the conductive film and the side wall portion.

Electrical components may be shielded using a shielding can or other shielding structure that covers the electrical components. The electrical components and the shielding structure may be mounted on a substrate such as a printed circuit board using solder or other conductive material. The shielding structure may have one or more shielding layers.
